Doctor Who

Doctor Who is both a British television series and a global multimedia franchise created and controlled by the BBC (British Broadcasting Corporation).

It centres on a time traveller called "the Doctor", who is often depicted as — but certainly not always — coming from a race of beings known as Time Lords. They travel through space and time in a time machine they call the TARDIS. This ship — which looks like a small, London police box on the outside — has nearly infinite dimensions on the inside. It has become such an iconic shape in British culture that it's currently the intellectual property of the BBC rather than its actual makers, the Metropolitan Police Service.

Since Doctor Who's revival in 2005, its production has been primarily based in Wales by BBC Wales, with its soundtrack regularly performed by the BBC National Orchestra of Wales since 2006.

In order to accommodate cast changes, the narrative allows the Doctor to regenerate into an essentially new person on occasion. The cast is rounded out by one or more "companions", often females. On average, the main cast completely changes once every three or four years — a significant factor in the longevity of the programme.

It has had two — some argue three — major production periods. The original run of the programme was from 1963 to 1989, and is often called the "classic series" or "classic Doctor Who". A failed revival, in the form of a Universal-BBC co-production, came in 1996 — but the resulting one-off telemovie is often considered a part of the classic series. The current form of the programme — sometimes called the "new series" — has been produced by BBC Wales and aired on BBC One since 2005.

Though the classic series is fondly remembered by fans of a certain age, the new series has been far more consistently popular with the British public, and is usually the highest-rated scripted drama — outside of perennially popular soap operas — in the weeks that it is on the air.

The franchise spawned by the main television programme includes dozens of distinct ranges of spinoffs in televised, audio and print media.

Origin
Several individuals share credit for establishing Doctor Who in 1963, but it is generally accepted that the original impetus for the series, as well as the establishment of certain aspects, such as the concept of the TARDIS, the basic character of the Doctor and the title Doctor Who itself belong to Canadian-born Sydney Newman, who is also credited with creating another iconic series, The Avengers. Others involved in piecing together the puzzle that became the series include Head of Serials Donald Wilson, writer C. E. Webber, script editor David Whitaker and the show's first producer, Verity Lambert, the first woman to hold such a position in the drama department at the BBC. Two other notable participants in the birth of the series were Anthony Coburn and Waris Hussein, the writer and director, respectively, of the first four-part serial, An Unearthly Child, the first episode of which aired on 23 November 1963. The version of the first episode that was broadcasted was in fact the second mounting of that episode; an earlier version (called "The Pilot Episode" by fans), was taped some weeks before, but was rejected for several issues. The BBC allowed a second mounting of the pilot to proceed. The first episode aired the day after the assassination of John F. Kennedy, and had to be rebroadcast a week later when power failures disrupted the first broadcast.

Also important to creating the atmosphere of the early series were composers Ron Grainer and Delia Derbyshire. Grainer wrote the basic melody of the Doctor Who theme, and Derbyshire, with the BBC Radiophonic Workshop, transformed it into a pioneering piece of electronica music. There have been several arrangements used of the theme, but the basic melody has remained unchanged throughout the show's history. No new piece of music has ever been commissioned as a theme, making it one of the longest-serving signature tunes in television history.

An Unearthly Child introduced the first incarnation of the Doctor, played by character actor William Hartnell. Supporting him were William Russell and Jacqueline Hill as Ian Chesterton and Barbara Wright, respectively, and Carole Ann Ford as the Doctor's granddaughter, Susan Foreman. These four would form the core cast of the series throughout its first season and into the second.

From very early on, the television show spawned a sub-genre of the franchise in the form of short stories in various shapes and forms from small one-paper issues to short novels to even telling a story on a set of cards. This genre has developed throughout the years into massive shorts and anthologies and is still holding up in the 21st century.

The Daleks
After the first episode introduced the characters and concept, the remaining three episodes of An Unearthly Child encompassed a modest storyline involving a group of cavemen in prehistoric times. The series began to find its voice as a science fiction series with the second serial, The Daleks by Terry Nation. It introduced the Daleks, the single most iconic reoccurring enemy of the franchise. The series began to really take off in popularity with this serial, which helped launch "Dalekmania" in the UK, leading to toys, the first novelisation Doctor Who in an Exciting Adventure with the Daleks, the movie adaptation Dr. Who and the Daleks, and many televised sequels, beginning with The Dalek Invasion of Earth.

Early cast changes
The Dalek Invasion of Earth was also notable for featuring the series' first cast change. Carole Ann Ford left the series. She was replaced the following week by Maureen O'Brien as Vicki, establishing the pattern of the Doctor's companions changing. The other original actors, William Russell and Jacqueline Hill, left the series a few months later at the conclusion of The Chase, making way for another new companion, Steven Taylor, played by Peter Purves. Over the decades, the length of service of different companions has ranged from as little as a few weeks (with some being considered companions after appearing in only a single episode), up to several years. Some actors have returned to reprise their roles years and even decades later (most notably Elisabeth Sladen as Sarah Jane Smith).

A change of identity
The next major turning point in the series occurred in 1966 when the actor playing the First Doctor, William Hartnell, left the series. Rather than introduce a new leading character, replace Hartnell with no explanation or simply cancel the series, the producers, with input from Sydney Newman, chose to establish the Doctor's ability to regenerate into a new person when injured or near death. This led to the dramatic — and successful — transition to Patrick Troughton as the Second Doctor at the conclusion of The Tenth Planet, a serial that was in itself notable for introducing the franchise's second most popular recurring villains, the Cybermen.

The intro for the 1967 serial The Macra Terror was iconic for incorporating the current Doctor's face to the sequence as a permanent instalment.

The Doctor's race was not established as being Time Lords until the last of Troughton's stories, The War Games in 1969. This story also featured the Doctor's home planet for the first time.

The experiment of regenerating the Doctor occurred again in 1970 with the introduction of one-time comic actor Jon Pertwee as the Third Doctor, a move that also coincided with the series changing to colour production. Once again, this was successful and Doctor Who continued to establish itself as a British TV institution, although it remained virtually unknown in American markets.

In 1973 the show celebrated its tenth anniversary, notably in its 10th season, with the story The Three Doctors, which also brought back former actors William Hartnell as the First Doctor and Patrick Troughton as the Second Doctor alongside Pertwee, in what would establish the Doctor being able to meet himself.

The name of the Doctor's planet, Gallifrey came in the 1974 story The Time Warrior, the term "regeneration", however, wasn't coined until the ending of Pertwee's era, Planet of the Spiders in 1974.

Target Books
In 1973, Target Books reissued a trilogy of novelisations from the mid-1960s, and in 1974 began to issue its own adaptations of televised episodes. In a time before home video recorders and commercial release of TV series on tape and DVD and when rebroadcasts were rare and many old episodes were thought lost, the Target line became a popular and valued aspect of the growing Doctor Who franchise; the books would be published into the mid-1990s. A unique feature of the Target line (in fact dating back to the first novelisations published by Frederick Muller) is that many of the books were written by either the original scriptwriters or by individuals with strong behind-the-scenes connections to the series, such as Barry Letts, Terrance Dicks, David Whitaker, etc., all of whom worked in script editing or producing capacities on the series. In the late 70s, about a dozen of the Target novels were reprinted in American editions by Pinnacle Books, with introductions by noted science fiction author Harlan Ellison, who added to the franchise's prestige by placing it higher in his estimation than Star Trek.

The Tom Baker years
The series continued through the 1970s, with Tom Baker taking on the role of the Fourth Doctor in 1974. Baker became the most iconic, and arguably most popular actor of the classic series. This was due in part to the frequent rebroadcasts of his episodes in the United Kingdom, which began during his tenure. He was the first "young" Doctor and played the role for more seasons (seven) than any actor to date. Other actors have been considered the "current" Doctor for longer, but without regular television appearances. Near the end of the Tom Baker era, the BBC attempted a spin-off series, K9 and Company, but it never went beyond a pilot episode, A Girl's Best Friend.

The US broadcasts of Doctor Who were initially poorly done, with some broadcasters airing a version with narration explaining the plot. By the late 1970s, however, the series was firmly entrenched in the Public Broadcasting Service (PBS), which would air the show repeatedly over the next three decades and air the revived series after 2004.

The 1974 serial Robot began featuring the TARDIS in the intro sequence, a feature that lasted until The Leisure Hive in 1980.

In 1976, season 13 episode 5 The Brain of Morbius aired, which saw a mindbending contest take place between the Doctor and evil Time Lord Morbius in which no less than 8 faces appeared meant to be faces of the Doctor prior to William Hartnell's First Doctor. While Philip Hinchcliffe would go on to state that he intended to imply that Hartnell wasn't the first, many fans of the show blatantly dismissed this, concluding that it either wasn't valid, that they were the faces of Morbius amongst others. Indeed multiple other stories would back these statements by firmly continuing to put Hartnell's version as being the original Doctor.

In 1979, Doctor Who saw its first comic strip story released in Doctor Who Weekly (later Doctor Who Magazine) with Doctor Who and the Iron Legion. This tradition has been constant with every issue of the magazine, except two.

The John Nathan-Turner era
Peter Davison succeeded Baker in 1981 as the Fifth Doctor with new producer John Nathan-Turner. Only twenty-nine when he was cast, Davison was, until the appointment of Matt Smith as the Eleventh Doctor in 2009, the youngest actor ever to play the Doctor officially. The TARDIS crew of the Fifth Doctor skewed younger and featured the first long-term companion's death when Adric died at the end of Earthshock. Two short-term companions had died earlier in one serial, The Daleks' Master Plan, but they had not been on the show more than a few weeks; Adric was on the series for about a year.

Davison's era was marked by experimentation by the BBC in terms of broadcast scheduling. The series moved to airing twice a week on weeknights, away from its traditional Saturday slot. Initially, this appeared to be a successful gamble. The ratings for Davison's early stories were on par with - if not higher than - Tom Baker's later stories. It was during Davison's era that the series marked its 20th anniversary in 1983 with the feature-length episode The Five Doctors. This featured all the actors who had played the Doctor to that time (although Hartnell and Tom Baker were shown in stock footage). It also was a first in the act of recasting the main actors as Richard Hurndall was cast in the role of the First Doctor, enabling this incarnation of the Time Lord to have an active role in the storyline, due to original actor Hartnell falling ill and dying in 1975.

The year 1983 also saw the release of the first ever Doctor Who video game, The First Adventure made for BBC Micro.

Davison did another season in 1984 before Colin Baker followed as the Sixth Doctor. With him the BBC further experimented with the format, moving from twenty-minute to forty-five-minute episodes. Nathan-Turner also experimented with the characterisation of the Doctor, intentionally making the Sixth Doctor initially unlikeable in order to create a new dynamic. Neither experiment was successful. Colin Baker's tenure was marked by a serious threat to the show's survival when the BBC, citing low ratings, announced it was ending the series after the 1985 season, its 22nd. Following immediate outcry, this decision was modified to become an eighteen-month hiatus. During the hiatus, fan efforts were launched to get the show back sooner. These included the recording of a charity record called "Doctor in Distress" by cast members. BBC Radio tried to fill the void by producing the first made-for-radio Doctor Who serial, Slipback, starring Colin Baker.

Following that, the BBC released another BBC Micro game, Doctor Who and the Warlord.

The series returned in 1986 with a season-long story arc, The Trial of a Time Lord, but with greatly reduced screen time. Fourteen episodes were allotted for the season, up from thirteen the previous season, but with episode lengths returned to twenty-five minutes. This was roughly half the storytelling time of recent seasons.

Along with that a third video game was released, now also created for computer, called Doctor Who and the Mines of Terror.

Although the TARDIS did not show up in the original title sequence, the 2019 special edition of Terror of the Vervoids, released with Season 23: The Collection, added the TARDIS to its title sequence.

End of an era
Although the show's return garnered sufficient ratings for the BBC to grant a stay of execution and renew it for a twenty-fourth season, Colin Baker's contract as the Doctor was not renewed and he ceded the role to Sylvester McCoy as the Seventh Doctor in 1987.

The series survived the hiatus, but never regained ratings needed for ongoing survival, constantly being beaten in the ratings by Coronation Street. Towards the end, it garnered ratings barely in the three million range, compared to eleven million at the peak of the Tom Baker era.

Attempts were made to refresh the ageing series by darkening the character of the Doctor through what was later called the Cartmel Masterplan (named for then-script editor Andrew Cartmel), and by introducing Ace, a companion with an edginess never before seen in an assistant.

The same year that McCoy took over, a fan-produced independent film, Wartime, was released. Taking advantage of a loophole in licensing that allows characters other than the Doctor to be licensed direct from their creators, this film featuring John Benton was the first of what would be a series of fan-made productions that would help keep the Doctor Who universe alive after 1989.

During McCoy's era, the series celebrated its 25th anniversary on TV. One of the year's serials, Remembrance of the Daleks, returned the Doctor to 76 Totter's Lane, where it all began in 1963.

Following production of the twenty-sixth season, Nathan-Turner learned that the show would not be renewed immediately for a twenty-seventh. After having McCoy record a series-ending monologue, the final episode — part 3 of the ironically titled Survival — aired on 6 December 1989, bringing Doctor Who's marathon 26-year run to a close. The Doctor Who Production Office closed down the following summer.

It has never been made clear whether the BBC ever actually "cancelled" Doctor Who in 1989, or simply put the series on hold. One of the first to state outright that the show was cancelled was co-star Sophie Aldred in the documentary More than 30 Years in the TARDIS.

Survival also marked the last time the Doctor's face was incorporated into the intro sequence, at least until 2012.

Although it was the end of an era, the McCoy years reinstated the feature of the TARDIS showing up in the intro sequence.

"The Wilderness Years"
The end of active production was made official in 1990. The Doctor Who Production Office was closed. The BBC never officially cancelled the series. It simply didn't commission any new episodes. This led to the launch of a cottage industry of spin-off work. These included the first long-term range of original fiction (the Virgin New Adventures series). Target Books exhausted all available remaining serials to novelise and the brand was retired in 1994. There were numerous independent video productions with characters and creatures from the series but never the Doctor himself, including the P.R.O.B.E. series featuring Liz Shaw. Many of their new actors, writers and directors would become involved in the main Doctor Who series, including Nicholas Briggs and Mark Gatiss. In 1993, the BBC made a half-hearted attempt at marking the thirtieth anniversary, first commissioning, then cancelling, a multi-Doctor special called The Dark Dimension. Instead they greenlit a brief, poorly received pastiche, Dimensions in Time, which aired as part of a Children in Need fundraiser and as a dubious crossover with the soap opera EastEnders.

For original fiction, Virgin's New Adventures picked up where Survival had left off. Over the next five years it greatly expanded the world of the Seventh Doctor, and Doctor Who, by featuring stories with more adult storylines than was possible on TV. The books also introduced the character of Bernice Summerfield, who was initially a companion of the Seventh Doctor. Over time she developed her own mini-franchise, which continues to this day.

Virgin also launched a similar series of books called the Virgin Missing Adventures, featuring past Doctors. One New Adventures novel, Damaged Goods, was written by a young writer who would later play a major role in the history of Doctor Who: Russell T Davies. Another future producer of the series, Steven Moffat, contributed short stories to Virgin's third line of Doctor Who fiction, the Virgin Decalogs. Around this time, Moffat also made his Doctor Who TV writing debut by penning the parody serial The Curse of Fatal Death. It aired as a fund-raiser for Comic Relief and starred Rowan Atkinson, Richard E Grant, Jim Broadbent, Hugh Grant, and Joanna Lumley as the 9th through 13th incarnations of the Doctor.

A false restart
The franchise's so-called "first interregnum" on television ended in 1996 with an attempt at launching an American-UK co-produced Doctor Who series. A television movie was produced for the American Fox Network, Doctor Who, in which McCoy handed off to Paul McGann's Eighth Doctor. Neither a reboot or re-imagining, the film was a continuation of the original series. While moderately successful on the BBC, it failed to garner sufficient ratings in the US to warrant a new series. McCoy, in a later interview with Doctor Who Confidential, postulated that the film failed in the US in part because viewers unfamiliar with the history of Doctor Who were confused by the first part of the film, which dealt with regeneration.

The movie made a one-off experiment of featuring a "cold opening", a scene before the intro sequence.

Back to the wilderness
The "second interregnum" that followed saw more novels (now published by the BBC under its BBC Books logo, featuring the Eighth Doctor), more independent productions, a separate series of Bernice Summerfield novels, a PC game called Destiny of the Doctors that saw Fourth-through-Seventh Doctor actors, Courtney and Ainley reprise their roles, and, in 1998, the start of a prolific series of officially licenced audio stories by Big Finish Productions. Same year, BBC Books and Big Finish would work together on a series of short books called Short Trips, and would continue that for years going forward.

Unlike the independent made-for-video productions, Big Finish could use Doctors and companions from the series. With the exception of Tom Baker, who wouldn't join Big Finish until 2012, and earlier Doctors now deceased, the audios featured the original actors. In particular, Big Finish produced a long-running series of programs continuing the adventures of McGann's Eighth Doctor. Big Finish also produced a prolific series of audio dramas featuring Bernice Summerfield (and began publishing novels featuring her once Virgin ended its series of books) as well as other spin-off series featuring other parts of the Doctor Who universe, such as Dalek Empire, I, Davros, Sarah Jane Smith and Gallifrey. Many of the writers, directors, and voice actors involved in this project also went on to work on the TV series proper.

The BBC also created new Doctor Who-related media projects during this time, creating several original webcast productions in conjunction with Big Finish, and making several Virgin-era Doctor Who novels available as e-books on its website.

The triumphant return
In 2003 for the 40th anniversary, the BBC released the 6-part webcast Scream of the Shalka, in which Richard E Grant was introduced as the Ninth Doctor. Intended to be an "official" continuation of the television series, this version of the character was soon after ignored by the 2005 series revival. The BBC stunned fans by announcing in 2003 that its Welsh production office, BBC Wales, had been given the go-ahead to produce a brand-new series of Doctor Who. The series would be produced by Russell T Davies and Julie Gardner. Davies, since his days writing Doctor Who fiction for Virgin, had gone on to create the critically acclaimed series,.

Meanwhile the BBC released two new video games on their website, TARDIS Tennis and Who Trumps.

In the following months, details of the new series emerged. Fans still questioned if the new series would be a continuation of the original series (a twenty-seventh season), or a re-imagining (as had recently occurred to great effect with Battlestar Galactica). Would the Paul McGann movie or Scream of the Shalka count? There was initial controversy when pop singer Billie Piper was cast as the new companion. The new series logo riled some fans; BBC News reported that some on the production team had received death threats over it.

The BBC's decision to restart the numbering of the series with series 1 in 2005 fuelled the debate over whether the new show would be a continuation. The BBC indicated it was strictly a commercial decision, and part of an overall strategy not to alienate new viewers by suggesting they needed to know twenty-six years of backstory.

Doctor Who returned to television in the spring of 2005. Christopher Eccleston took over from McGann as the Ninth Doctor. After initial uncertainty, it was soon established the new series was a continuation of the old. The new episodes returned Doctor Who to levels of popularity not seen since the 1970s, and garnered awards the original series never saw. Eccleston's brief era marked the return of UNIT, the Autons, the Nestene Consciousness, the Daleks and the Dalek Emperor to television, as well as the introduction of Jack Harkness, who would become a recurring character during the Russell T. Davies era. In March 2006, the new series was first broadcast in the United States on the SciFi Channel. Audiences embraced the new series, with Billie Piper's Rose Tyler, in particular. The second episode The End of the World began a new tradition of featuring a scene before the intro sequence, a "cold opening".

The show stumbled slightly with the announcement days after its premiere on 30 March that Eccleston was leaving after a single season. The BBC later apologised for the timing of this announcement. The tenure of his replacement, David Tennant's Tenth Doctor, was dominated by the relationship between the Doctor and Rose Tyler, a closer bond than even the "Mentor" type relationship shared between the Seventh Doctor and Ace. Tennant's era also saw the return of Sarah Jane Smith in School Reunion, the episode most cited as the one that established once and for all that "nuWho" was a direct continuation of the 1963-89 series. This was followed by the Children in Need mini-episode Time Crash, in which Peter Davison reprised his role as the Fifth Doctor.

In 2005, four online video games were released by the BBC, most notably Attack of the Graske.

Tennant's era also saw the reintroduction of the Cybermen, albeit a parallel version. Related to this, the series began delving into the multiverse concept with Rise of the Cybermen, a topic that would dominate the final episodes of the fourth series in 2008.

Since the show's return to TV, Doctor Who has become a major franchise. It spawned two successful spin-off series in quick succession: Torchwood and The Sarah Jane Adventures; both centred around the adventures of former companions. There was a third, non-BBC spin-off, K9. Two documentary series were launched with the return of Doctor Who: Doctor Who Confidential, (2005-2011) and Totally Doctor Who (2006-2007). The last series also produced the first animated-for-television Doctor Who serial, The Infinite Quest, which aired in 2007 and featured Tennant. A second animated serial, Dreamland, aired in 2009.

The year 2006 had the pleasure of welcoming 17 new online games, many of them featuring some of the newly introduced aliens, amongst them Daleks v Cybermen, Ood Escape and The Wire.

The Tennant era also saw the start of a new tradition in late 2005: the Doctor Who Christmas Special, holiday-themed episodes aired separately from the regular seasons. , thirteen such specials have been aired. The series has also contributed several mini-episodes, such as the aforementioned Time Crash, to the Children in Need Appeal and the BBC Prom concert series (Music of the Spheres).

The 3-part conclusion of the third revived season in 2007 saw the inclusion of the Master in not one, but two different incarnations, not seen since the TV movie in 1996.

Ten new online video games were released by the BBC in 2007, with one of them, Bane Blaster, based on the first SJA-story.

The fourth revived season in 2008 saw the return of the Sontarans in episodes 4 and 5, The Sontaran Stratagem/The Poison Sky, for the first time since The Two Doctors in 1985. The season-conclusion, which linked all four series together and featured the return of Rose and other companions, saw Doctor Who garner its highest ratings in nearly thirty years. It further saw the first return of Dalek creator Davros since Remembrance of the Daleks. It was followed by the 2008 Christmas special, The Next Doctor, which included a scene — the first of its kind — in which all ten Doctors, including the debated Paul McGann's Eighth Doctor, were shown, firmly establishing the Eighth Doctor's place in his personal history.

This year saw the release of 11 new online games as well as one, Top Trumps: Doctor Who, for PC, PS2 and Wii and DS.

The transition
The year 2009 was a transition year for Doctor Who in terms of both production and releases. The series had only four episodes, aired as specials in April, November and on Christmas Day and New Year's Day 2010. These specials and an animated serial, Dreamland, marked David Tennant's final appearances as the Tenth Doctor. The decision for the series to take a break following series 4 was, according to Davies' book The Writer's Tale, planned as far back as Tennant's first year. Davies devised the break to smooth the transition between his term as show-runner and that of Steven Moffat, whom he invited to take over his post as executive producer and lead writer when the series returned as a weekly programme in 2010. Tennant took advantage of this break to appear in a high-profile stage production of Hamlet co-starring Star Trek icon Patrick Stewart, which some media erroneously indicated was the reason for the break.

The announcement of the gap year was followed by the announcement that Davies and Julie Gardner would be stepping aside as executive producers of Doctor Who following the specials. Moffat, who won the Hugo Award three years running for his Doctor Who scripts, was appointed new head writer and executive producer. Also appointed executive producers were Piers Wenger and Beth Willis.

The question of whether Tennant would stay on was a hot topic in the UK media for much of 2008. On 19 October 2008, Tennant, while accepting his National Television Award for Favourite Actor, announced he would leave the role after the specials. After months of speculation, it was announced on 3 January 2009 that twenty-six-year-old Matt Smith would join the series in 2010 as the Eleventh Doctor, smashing Peter Davison's record as the youngest Doctor ever.

The end of Series 4 and the start of the specials marked a "changing of the guard" for international broadcasts of the series in the US and Canada. In the US, the SciFi Channel relinquished first-broadcast rights to BBC America. In Canada, the CBC's controversial handling of the series (which had seen a marked decrease in network interest and destructive editing of the Series 4 finale for commercials) came to an abrupt end when the cable network Space adopted the series. Both began airing the series with The Next Doctor in the spring of 2009 and announced they would air the weekly series in 2010.

The first gap-year special, Planet of the Dead aired during Easter 2009. Planet of the Dead was the first Doctor Who episode to be filmed in and, subsequently, the first to be issued to Blu-ray.

Meanwhile, Torchwood aired its third series in July 2009, now on BBC One, but in a different format: a single, critically acclaimed, five-episode story entitled Children of Earth. It also aired to acclaim and high ratings on BBC America and Space. The Sarah Jane Adventures began its third series in October 2009, with David Tennant playing the Doctor in two episodes. Work on a non-BBC spin-off series, K9, also progressed through the year.

The second special of the "gap year", The Waters of Mars aired on 15 November 2009, and an animated adventure, Dreamland, was broadcast serialised on the BBC's Red Button service before being aired as one programme by the BBC proper.

The same year saw the release of six new online video games, one of which, The Waters of Mars, based on the TV story of the same name.

During the Christmas season, Tennant appeared as the Doctor in a series of Christmas idents for the BBC. Finally, the era of the Tenth Doctor ended with the two-part special The End of Time. Part 1 aired on 25 December 2009 and the concluding Part 2, with David Tennant handing over the role to Matt Smith, aired on 1 January 2010. The finale further saw the return of and the brief return of the Time Lord High Council and Gallifrey from inside a time lock.

That same year, the BBC Books stopped productions of the original format of the Short Trips series. Big Finish Productions took full control and resurrected the series as short audio stories going forward.

The new man
Production of the first Matt Smith episodes commenced in July 2009. Writers recruited for the new season included Richard Curtis (co-creator of and writer of ) and Toby Whithouse (creator of ). Noted fantasy writer Neil Gaiman was rumoured to be involved in the new season. These rumours proved to be incorrect, but he did end up penning The Doctor's Wife the following series. Michael Moorcock, another noted fantasy novelist, also announced he was writing a Doctor Who novel for publication in 2010.

Minor competition for Smith arrived in January 2010 when broadcasts of the non-BBC series K9 began in parts of Europe. The UK, which had seen a preview of the first episode on Halloween 2009, saw the series debut on Disney XD on 3 April 2010, a few hours before the start of the fifth series.

After months of intense publicity, the Matt Smith/Eleventh Doctor era officially began on 3 April 2010 with the broadcast of The Eleventh Hour on BBC One. In a show of international support for the series, broadcasts in the US, Canada, Australia and New Zealand were scheduled within a few weeks, the first time the programme's biggest international markets had coincided their broadcasts in this way.

The fifth series ran for thirteen weeks, concluding with The Big Bang on 26 June 2010, which saw the biggest amount ever of villains gathered in one story, even including spin-off villains. Before the first episode of series 5 was broadcast, the BBC announced that a Christmas special had been commissioned for 2010, and a sixth series of the revived series was scheduled to enter production that summer for broadcast in 2011.

Torchwood aired its fourth and final series, Miracle Day in 2011. It was a collaboration between BBC & BBCAmerica, exploring the aftermath of a day when nobody dies. It saw the return of Captain Jack Harkness and Gwen Cooper as well as the introductions of Esther Drummond and Rex Matheson. Episode One aired on 14 July and the series wrapped on 9 September 2011.

Series 6 aired in two parts; the first half aired in the spring and the remaining episodes aired in the autumn. The BBC claimed the split was to accommodate a story arc with a mid-season cliffhanger, the arc being the revelation of the identity of River Song. Steven Moffat was said to have requested the split. Episode 4, The Doctor's Wife, also featured the first mention of a Time Lord, the Corsair, being able to change gender between regenerations.

Series 7 aired in two parts as well, although this time the first half aired in the autumn and the second half aired in the spring, with a Christmas special in between. Broadcasts began in September 2012, with Asylum of the Daleks.

This Special reintroduced the concept of the current Doctor's face showing up in the intro sequence, last seen in 1989's Survival. It also brought back the Great Intelligence for the first time since 1968's The Web of Fear.

The first few years of the 2010s welcomed a plethora of new games for different platforms, some of them featuring major gameplay for the first time, such as City of the Daleks, Blood of the Cybermen and TARDIS.

50 years and beyond
Following the series 7 finale, The Name of the Doctor, The Day of the Doctor aired on TV and in cinemas on 23 November 2013 to celebrate the programme's 50th anniversary. This heavily featured a new Doctor, played by John Hurt, who was revealed to be the true ninth incarnation of the Doctor in a mini-episode titled The Night of the Doctor, which had Paul McGann return as the Eighth Doctor and regenerating him. The 50th also featured Tom Baker himself returning, however as a character known to the Doctor, called the Curator, as well as a cameo of the immediate successor of Smith. It featured the original 1963 intro sequence and a brief one-off departure of showing the Doctor's face and the TARDIS in the sequence, not counting the mini-episode in the case of the former.

Big Finish Productions also celebrated the 50th Anniversary of the show with the audio story The Light at the End on the 23 October, featuring the first eight incarnations of the Doctor as well as a couple of their companions with the Master as the villain.

The Christmas special The Time of the Doctor was broadcast a month later on 25 December. Time revealed that the Eleventh Doctor was the final incarnation before he was granted a new cycle of regenerations. It also featured the Eleventh Doctor's regeneration into Peter Capaldi's Twelfth; Capaldi was announced as the Twelfth Doctor in a live special months earlier on 4 August.

With the successful release of the 50th anniversary special, the Series 8 premiere, Deep Breath, was extended and broadcast simultaneously on TV and theatres on 23 August 2014. Notably, Peter Capaldi's debut as the lead featured a surprise cameo from his predecessor Matt Smith, the first such occurrence of an immediate reprisal in Doctor Who. Broadcasting its run, now reduced from 13 to 12 episodes, without a split, Series 8 concluded with Death in Heaven on 8 November, just less than two months before the 2014 Christmas special. Death in Heaven featured a one-off change in the intro sequence, showing companion Clara Oswald's face instead of the Doctor's as a response to the preceding "cold opening". The series featured a mysterious woman known as throughout most episodes, who by the conclusion was revealed as a female incarnation of the Master.

Starting just short of a month later in 2015, Series 9 began with The Magician's Apprentice on 19 September and concluded with Hell Bent on 5 December, only twenty days before The Husbands of River Song on Christmas Day. The intro for Before the Flood featured rock-guitar play over the theme while specially filmed "found footage" story Sleep No More featured a one-off intro sequence matching the "feel" of the story, getting rid of both the TARDIS and the Doctor's face.

2016 would see another break for Doctor Who on TV while the next series was filmed to broadcast in the following year, with a unique teaser introducing the new companion releasing on 23 April. 22 October marked the premiere, fittingly on the 10th anniversary as that of Torchwood, of a new but ultimately ill-fated spin-off series: Class. Airing exclusively on BBC Three, which had since been relegated to an online service, Class was based at Coal Hill School, the very first setting of Doctor Who, and hosted a guest appearance by the Doctor himself in the first episode. Ultimately, the sole new episode of Doctor Who itself to air in 2016 would be the annual Christmas special: The Return of Doctor Mysterio, the first in five years to preview the upcoming series as Doctor Who would return to the spring season.

Series 10 premiered with The Pilot on 19 April. The series concluded with The Doctor Falls on 1 July, which saw the Doctor mortally wounded. The Doctor himself would postpone his regeneration, however, and the finale concluded with the surprise return of the First Doctor now portrayed by David Bradley, who had previously played William Hartnell in the 50th anniversary docudrama An Adventure in Space and Time, who would go on to expand the First Doctor's timeline beyond his original final story with the Christmas special Twice Upon a Time, incorporating footage from The Tenth Planet by morphing Hartnell into Bradley and vice versa (thereby also showing his regeneration again). Soon after The Doctor Falls, Jodie Whittaker was announced to be playing the Thirteenth Doctor, the first female incarnation of the Doctor, who made her debut at the conclusion of said Christmas special. The finale of the series, beginning in World Enough and Time, saw the return of John Simm as alongside Gomez's Missy, marking the first televised Multi-Master story in the show's history.

The mid-2010s saw further video game releases such as Legacy and Infinity as well as the first multi-franchise LEGO game, LEGO Dimensions. A mini-game on the Doctor Who Instagram Stories game was also released in November 2018, with another one released in April 2019.

A huge milestone
With new incoming showrunner Chris Chibnall taking over, a huge milestone was reached when the first ever woman, Jodie Whittaker was cast as the Doctor and given a plethora of diversified episodes. Series 11 was moved to Sundays and was reduced to 10 episodes beginning with The Woman Who Fell to Earth on 7 October 2018 and concluding with The Battle of Ranskoor Av Kolos on 9 December, compensating with an extended running time. The new change was met with a large amount of positivity, with majority praising the new Doctor and stories, many celebrities saying it was about time. Some people, however, were not very impressed with the changes made, calling them "too politically correct" and "Social Justice Warrior"-driven. Despite this negativity, the new era ended up very successful. The new series also got rid of the annual Christmas Special, which had been a constant since the return in 2005, replacing it with a New Year Special on Tuesday the 1 January 2019, followed by a gap year.

This series also once again got rid of the idea of having the current Doctor's face as well as the TARDIS show up in the intro. It also removed the "cold openings" which had been permanent instalments since 2005's The End of the World. The opening story and the Special also didn't have a title sequence.

As for first-timers, 2019 saw the release of a fully fledged virtual reality game The Runaway and the first ever escape room Worlds Collide on the 16 May and 16 January, respectively. It was also the first time a Doctor appeared in expanded media before appearing on-screen.

2019 was also the year that Big Finish Productions celebrated their 20th Anniversary. This was done with a free YouTube livestream spanning the entire weekend of 20 and 21 July with a plethora of audio stories ending with Lies in Ruins, the opening of the 20th anniversary audio box set The Legacy of Time.

August saw a third Instragram mini-game released to the Stories section.

All throughout the last months of 2018 and the first 9 months of 2019, students, staff and graduates of the University of Central Lancashire (UCLan) had worked tirelessly and carefully in collaboration with the Doctor Who team to recreate the missing 1965 single-episode story Mission to the Unknown as closely as possible to the original and with the original 60s-era television values. It was released on YouTube on 9 October 2019, giving fans the opportunity to again enjoy the lost classic.

17 October 2019 marked the 40th anniversary of the long-running Doctor Who Magazine with its 544th issue being released exactly 40 years after the first issue. To celebrate, the issue also offered a 32-page Doctor Who Magazine: The Index along with it at no additional cost.

A Doctor Who theme night at the Natural History Museum in Kensington as part of their after-hours series Lates was held on 25 October 2019. A special screening of the Series 3 opening episode, Smith and Jones, was shown during the event.

On the 12 November 2019, a second VR game was released called The Edge of Time, in which the Player got much more freedom to explore time and space as well as piloting the TARDIS. Essentially, the Player gets sent on an adventure of their own.

Series 12 premiered on New Year's Day, Wednesday 1 January 2020 with Spyfall: Part One, which also marked the first time since The End of Time that a two-part story had a single title. Part One also aired on the 10th Anniversary of The End of Time: Part Two. Spyfall: Part Two was broadcast only four days later on 5 January on a Sunday which continued to be the format established the previous series.

Episode 5 of series 12, Fugitive of the Judoon; broadcast on 26 January, hit another milestone as the first episode to have a black woman, Jo Martin, cast as |the Doctor, albeit adding confusion to the show's history, with this version claiming to be a past version while the Thirteenth Doctor has no recollection of her. This episode also brought back Captain Jack Harkness over a decade after his last appearance on the show, The End of Time: Part Two and 9 years after his last televised appearance, in Torchwood: Miracle Day's last episode The Blood Line.

The series ended on 1 March 2020 with The Timeless Children, once and for all establishing to the lore of the show that the Doctor had lived for several millennia before becoming the First Doctor, by not only settling the decades-long debate of the "Morbius Doctors" from The Brain of Morbius, but also implying vaguely "the Ruth Doctor" to be from the Doctor's past before William Hartnell's incarnation while also giving the character a new background as a being from another dimension known as "the Timeless Child" capable of infinite regeneration who was brought to Gallifrey by the Shobogan Tecteun, who went on to transfer the regenerative ability to the people of the planet and thus creating the Time Lords. This release created a gap between stories with a little over half a year until the following story.

Series 12 also saw the "cold opening" return for the first time since 2017's Twice Upon a Time, though it was not used consistently across all episodes.

2020 saw the release of the Doctor Who franchise's second escape room A Dalek Awakens, launching on 9 March 2020.

Six months later, the first print-and-play escape room was released on 8 August, called The Hollow Planet and intended as a prequel to the previous escape room.

A little over half a year later after The Timeless Children, the New Year Special aired on 1 January 2021, named Revolution of the Daleks and continuing the Dalek-storyline begun in Resolution with a a new mutated faction of Daleks introduced leading to civil war between them and a squad of pure Daleks similar to the war fought between Imperial Daleks and Renegade Daleks in Remembrance of the Daleks. The story also saw the return of Jack Robertson from Arachnids in the UK as well as the second return of Jack Harkness, also bringing in multiple numbers of creatures from the Doctor’s past adventures.

COVID-19
On 25 March 2020, Chris Chibnall published a short story to the Doctor Who website titled Things She Thought While Falling, set between Twice Upon a Time and The Woman Who Fell to Earth. It was written as a treat to take fans' minds off of the COVID-19 outbreak worldwide.

On 26 March 2020, Russell T Davies returned to publish a previously withheld short story titled Doctor Who and the Time War, which offered an alternate account on what happened during the Last Great Time War, namely having the Eighth Doctor destroy Gallifrey and subsequently regenerating into the Ninth Doctor completely omitting the existence of a War Doctor. Later, Davies also released a new audio short story titled Revenge of the Nestene set directly after Rose. Both were part of a Doctor Who: Lockdown! event due to COVID-19.

This started an era of multiple releases of short stories, webcasts and alternate script-reveals which featured alongside watchalongs of various episodes of Doctor Who throughout the entire year 2020 as a way for fans to cope with the virus spreading across the world and forcing new restrictions on people constantly, extending its way into February 2021.

The biggest of these stories was the massive multi-media expanding series known as Time Lord Victorious, released on 17 August, and played off of the Tenth Doctor's self-proclaimed title in 2009 story The Waters of Mars, which sent the Doctor down a long path of saving the universe from Time Fractures caused by him meddling with time, all while avoiding his own death. While the plot of time fracturing continued later down the line, this series ran until to 16 April 2021.

On 19 March 2021, an iOS and Android game was released by Maze Theory, called The Lonely Assassins, set around the Wester Drumlins disappearances and featuring Weeping Angels as well as the Player as the hero.

Post-Lockdown
On 26 May a new massive ground-breaking Immersive Theatrical Adventure, known as Doctor Who: Time Fracture, opened its doors in Davies Mews in London to the public, promising an exciting adventure where the visitor got to be the hero of the day.

This immersive theatre had the entire plethora of known Doctors as well as some friends and companions returning via pre-recordings to guide the hero through it all while helping to avoid foes along the way such as Daleks, Cybermen and Weeping Angels.

The experience would be running throughout all of 2021 as well as going well into 2022, closing down on 5 June of that year.

On 25 July was released a trailer for the upcoming series, which included a link to a "/mystery" page on the Doctor Who website which began a quest on 13 August of clue-finding in an ARG known as #FindTheDoctor meant to engage fans until the series. The ARG dropped clues on a weekly basis up until 16 September, as a reward releasing a promo pic of Thirteen and a video revealing a new monster.

On 24 September it was revealed that Russell T Davies would be returning to take over as showrunner, with his new reign officially starting in November 2023, but unofficially starting 23 October 2022. This was accompanied by a new deal between the BBC and Bad Wolf Productions, which had simultaniously been acquired by Sony Pictures Television, to be co-producing the following era.

On 14 October, a follow-up to The Edge of Time was released, called The Edge of Reality, which functioned much in the same way that the preceding game did, but offered a much more expanded gameplay and saw the return of David Tennant voicing the Tenth Doctor, alongside Jodie Whittaker's Thirteenth Doctor.

Series 13, subtitled Doctor Who: Flux, was reduced to 6 episodes as a result of COVID-19 and was released on 31 October with its first episode The Halloween Apocalypse. On 5 December the sixth and final episode of this series, The Vanquishers aired, forming a serial for the first time since Season 26 in 1989 and the first time the entire season is a single story since The Trial of a Time Lord (season 23) in 1986. It saw the continuation of the Timeless Child storyline, uncovered in the previous year's The Timeless Children, revealing the Fugitive Doctor's involvement with the Division in their quest to stop the Dark Times at the hands of Ravagers Swarm and Azure along with her then-companion Karvanista and other operatives, hiding time-creatures, the Mouri inside living prisons designated Passenger forms. It introduced Dan Lewis as a new companion, after being unwillingly swept away from his love Diane, and saw the return of Tecteun in a new incarnation as well as the Sontarans, Daleks, Weeping Angels, Cybermen and an Ood and introduced a universe-breaking force known as the Flux, meanwhile a girl named Claire Brown dealt with a Squad of Weeping Angels and an ordinary man, Professor Jericho joined in on a trip of a lifetime. It also saw the return of Kate Stewart and gave Joseph Williamson's mysterious tunnels a purpose and saw a lover's story between characters Bel and Vinder while an evil mastermind the Grand Serpent secretly infiltrated and climbed the ranks of UNIT, ultimately shutting it down in 2017. It also brought an element from the Virgin New Adventures novels to the screen in the form of the Eternal Time.

A Special era
A few weeks after, the New Year Special aired on 1 January 2022, titled Eve of the Daleks. It saw the introduction of the Dalek Execution Squad to the screen, fighting a time loop to kill the Doctor in revenge for destroying their War Fleet in the Flux.

As a new first, Doctor Who teamed up with the massive multiplayer online roleplaying game EVE Online on 13 January to create a limited time online adventure game called The Interstellar Convergence. It lasted until 1 February.

On 17 March, Doctor Who created an island in the massive multiplayer game Fortnite. In this game the player would see a lot of familarities such as Gallifrey, Kerb!am, the Kerb!am Man, Daleks, Weeping Angels, the Pting and so on, as they would compete in a battle royale. The game was unassociated with Fortnite’s creator Epic Games, but carried the label "Created in Fortnite".

On 1 April a boardgame was released by Gale Force Nine called Don't Blink which saw the Eleventh Doctor and his companions facing off against the Weeping Angels on a spaceship while trying to repair the TARDIS.

On 17 April the second ever Easter Special Legend of the Sea Devils aired, and reintroduced the Sea Devils to the show for the first time since 1984 story ''Warriors of the Deep.

Immediately following the special, BBC Sounds aired a new audio spin-off series in 10 parts called Doctor Who: Redacted, episode one of which was called SOS, which dealt with a team of young people running a podcast called The Blue Box Files, a show about trying to figure out what the mysterious blue box showing up throughout history could mean. The show dealt with the mystery of the Doctor and people known to them being "redacted" from history. The series concluded with Salvation on 19 June, which saw the Doctor return to reality and Cleo Proctor saving the universe.

On 27 June, Eastside Games released a new video game for iOS mobile phones called Lost in Time, which saw the Thirteenth Doctor, Twelfth Doctor, Tenth Doctor and Fourth Doctor and their friends trying to prevent a sinister plot from tearing apart the universe. The game was only a "soft-launch" at that time, with the full release taking place on 8 March 2023.

The British Broadcasting Corporation had its 100th Anniversary on 18 October 2022, celebrating its creation on 18 October 1922 with a BBC 100 event across a week. As part of the celebrations Doctor Who aired a Centenary Special on 23 October 2022, The Power of the Doctor, which incidentally also happened to be the end of an era as it was the last episode written by Chris Chibnall as well as Thirteenth Doctor star Jodie Whittaker. It saw companion Dan leaving the TARDIS early on, and saw Yaz and the Doctor face off against the combined forces of the Daleks, the Cybermen and the Master in a battle that ultimately caused the Doctor to regenerate. It saw the return of Graham O'Brien, Kate Stewart, Inston-Vee Vinder, Ace, Tegan Jovanka and Ashad, the Lone Cyberman as well as brief appearances from Melanie Bush, Jo Jones and Ian Chesterton. Also returning were the faces of former Doctors, the First, the Fifth, the Sixth, the Seventh, the Eighth and the Fugitive, both as Guardians of the Edge at the Time Lord-dreamstate afterlife and as AI interfaces. It saw the return of David Tennant as the new Fourteenth Doctor in a surprise twisted turn of events.

On 25 October, it was officially announced as part of a deal between the BBC/Bad Wolf Productions and Disney Branded Television that future series of the show would be available outside the U.K. and Ireland on the streaming platform Disney+, transforming Doctor Who into a global franchise.

On 1 November, the cross-platform, massively multiplayer, party royale game Fall Guys released four new character-skins available for purchase. These were a Dalek, the Fourth Doctor, the Thirteenth Doctor and the Fourteenth Doctor. The skins were available until early morning 6 November (adverttised as 5 November).

On 10 November, an "unprecedented" move was made with the then-latest issue of Doctor Who Magazine, issue #584, in that it released the first full story of the new incarnation of the Doctor, called Liberation of the Daleks, which would be a multi-issue comic strip, covering the gap between The Power of the Doctor and the next television story.

Continuity
A common contention among fans and producers of the series is that a large part of the Doctor's appeal comes from their mysterious and alien origins. While over the decades several revelations have been made about their background — that they are a Time Lord, that they are from Gallifrey, they can regenerate a total of 13 times, among others — the writers have striven to retain some sense of mystery and to preserve the eternal question, "Doctor who?" This backstory was not rigidly planned from the beginning, but developed gradually and haphazardly over the years, the result of the work of many writers and producers.

Understandably, this has led to continuity problems. Characters such as the Monk were retroactively classified as Time Lords, early histories of races such as the Daleks were rewritten, unseen versions of the Doctor existed prior to William Hartnell's version and so on. The creation of a detailed backstory has also led to the criticism that too much being known about the Doctor limits both creative possibilities and the sense of mystery. Some of the stories during the Seventh Doctor's tenure, part of the so-called "Cartmel Masterplan", were intended to deal with this issue by suggesting that much of what was believed about the Doctor was wrong and that they are a far more powerful and mysterious figure than previously thought. In both an untelevised scene in Remembrance of the Daleks and the subsequent Silver Nemesis it is implied (to quote an excised line from "Remembrance") that the Doctor is "far more than just another Time Lord." The suspension of the series in 1989, however, meant that none of these hints were ever resolved, at least on television. The Virgin New Adventures novel, Lungbarrow, did resolve these hints and explain the Doctor's origins. However, not all fans regard the spin-off novels as canon or accept the revelations made in that particular story, partly because other parts of the franchise seem to contradict parts of it.

The 1996 television movie created even more uncertainty about the character, revealing that the Doctor had a human mother and they remembered their father. Fans, however, seemed to be more upset about the fact that the Eighth Doctor kissed Dr Grace Holloway, breaking the series' longstanding taboo against the Doctor having any romantic involvement with their companions.

The revelation in the 1996 television movie that the Doctor was half-human is often considered to be a continuity error as the Doctor is considered by most to be a full Time Lord, causing fans to attempt to find alternative explanations about why the Doctor claimed to be part human.

While some fans regard discontinuities as a problem, others regard it as a source of interest or humour — an attitude taken in the book The Discontinuity Guide. A common fan explanation is that a universe with time travellers is likely to have many historical inconsistencies.

The revived series has tackled this issue head on by suggesting that "time is in flux" and with the exception of certain fixed points in time, almost anything can be changed. Recently, some fan interpretations of the series 5 finale, The Big Bang, have suggested a potential reboot of Doctor Who continuity in toto, but there is also evidence in opposition to this view.

In 2020, the 12th revived series took another bold move to shake up the mythos of the show, by claiming the Doctor's origins are a completely different species to what was previously established, that they are from a different universe and that they can regenerate an infinite number of times.

There has been much fan speculation on exactly which aspects of the television series, books, radio dramatisations, and other sources are considered canon. This has been made more complex by the fact that at least one novel, short story, comic, and audio have all been adapted for the TV series. Additionally, the events of at least one novel have been referenced on screen. For their part, the BBC have never issued a firm edict as to what counts as "canon". Thus, Doctor Who stands in stark contrast to the more formalised canons of Star Trek, Star Wars, Harry Potter, The Lord of the Rings — and, indeed, almost every other fictional universe.

"Doctor Who?"
When the series began, nothing was known of the Doctor at all, not even their name. In the very first serial, An Unearthly Child, two teachers from the Coal Hill School in London, Barbara Wright and Ian Chesterton, become intrigued by one of their students, Susan Foreman, who exhibits high intelligence and patchy, unusually advanced knowledge. Trailing her to a junkyard at 76 Totter's Lane, they encounter a strange old man and hear Susan's voice coming from inside what appears to be a police box. Pushing their way inside, the two find that the exterior is actually camouflage for the dimensionally transcendental interior of the TARDIS.

Susan calls the old man "Grandfather", but he simply calls himself the Doctor. When he fears Ian and Barbara may alert the local authorities to what they've seen, he whisks them all away to another place in time and space.

In the first episode, Ian addresses the Doctor as "Doctor Foreman," as the junkyard in which they find him bears the sign "I.M. Foreman". When addressed by Ian with this name in the next episode, the Time Lord responds, "Eh? Doctor who? What's he talking about?" Later, when Ian realises that "Foreman" is not his name, he asks Barbara, "Who is he? Doctor who?" Although listed in the on-screen credits for nearly twenty years as "Doctor Who", the Doctor is never really called by that name in the series, except in that same tongue-in-cheek manner. For example, in The Five Doctors when one character refers to him as "the Doctor", another character asks, "Who?" The only real exception has been the computer WOTAN, in the serial, The War Machines, which commanded that "Doctor Who is required."

In The Gunfighters, the First Doctor uses the alias. In The Highlanders the Second Doctor assumes the name of "Doctor von Wer" (a German translation of "Doctor of Who"), and signs himself as "Dr. W" in The Underwater Menace. In The Wheel in Space, his companion Jamie, reads the name off some medical equipment, and tells the crew of the Wheel that the Doctor's name is "John Smith". The Doctor adopts this alias several times over the course of the series, often prefixing the title "Doctor" to it. This has continued to the Tenth Doctor, and was famously referenced to in the 1996 television movie, where even though the Doctor is unconscious, a complete stranger, seemingly at random, writes the name John Smith on the Doctor's hospital admission papers.

In The Armageddon Factor, the Time Lord Drax addresses the Fourth Doctor as "Thete", short for "Theta Sigma", apparently a University nickname. In the 1988 serial Remembrance of the Daleks, the Seventh Doctor is asked to sign a document, which he does by using a question mark, and produces a calling card with a series of Greek letters (or Old High Gallifreyan script) and a question mark inscribed on it. The Eighth Doctor briefly used the alias "Dr Bowman" in the 1996 television movie. He has also been mocked by his fellow Time Lords for adhering to such a "lowly" title as "Doctor".

In many spin-off comic strips, books, films and other media, the character is often called "Doctor Who" (or just "Dr. Who") as a matter of course, though this has declined in recent years. From the first story through to Logopolis (the last story of Season 18 and also of the Tom Baker era), the lead character was listed as "Doctor Who". Starting with Peter Davison's first story, Castrovalva (also the first story of Season 19), the lead character is credited simply as "The Doctor".

Doctor Who writer Terrance Dicks offered the theory that Time Lord names were "jawbreakers," long and extremely difficult to pronounce, and this was why the Doctor never revealed his true name. However, River Song, one of the few people ever to know his name, was able to whisper it in his ear in a very short time. Some fans have speculated, taking off from the fact that the full name of the Time Lady Romana is "Romanadvoratrelundar", that the first syllable of the Doctor's true name is "Who". It should be noted that, although it is often asserted that "Doctor Who" is not the character's name, there is nothing in the series itself that actually confirms this. On at least one occasion the Doctor is about to give a name after the title "Doctor..." but is interrupted. Interestingly, the BBC novel, The Infinity Doctors mentions an ancient Gallifreyan god named "OHM". When this name is turned upside down, the result is "WHO." This idea originated in early drafts of The Three Doctors by Bob Baker and Dave Martin. The character of "Ohm" eventually became Omega.

It is interesting to note that, while spin-off media is known to "fill in the blanks" regarding aspects of Doctor Who lore — for example, several novels "revealed" The Master's real name — no officially licensed media has ever seriously attempted to solve the riddle of the Doctor's real name. Notwithstanding early spin-off media that treated "Doctor Who" as his name, of course.

The Tenth Doctor, played by David Tennant, has stated that there was only one reason and one time that he would or could reveal his true name. During Matt Smith's reign as the Eleventh Doctor, it was revealed that the oldest question in the universe was "Doctor Who?" and considering how desperate the Silence, a religious order devoted to destroying the Doctor, were to keep him from revealing it, the consequences of him telling anyone his real name must be catastrophic.

In The Bells of Saint John, the Eleventh Doctor asked Clara Oswald to repeat the question, and stated that he didn't realise how much he enjoyed people asking him "Doctor Who?"

The name of the Doctor was a huge topic throughout the entire Eleventh Doctor era, with various aliens throughout the show gathering to imprison the Doctor to prevent him from eventually reaching the planet Trenzalore and speak his real name which in turn would restart the Time War by letting the Time Lords back into the universe before it was safe.

Accolades
In 2000, in a poll of industry professionals, the voted Doctor Who #3 in a list of the. Since its return in 2005, the series has received many nominations and awards both nationally (UK) and internationally. This includes BAFTAs, the National Television Awards and the Hugo Awards. American accolades have been fewer and farther between, although in 2007 it broke a barrier by receiving a nomination for the 2008 People's Choice Awards, although it did not win. The series' revival found its highest ratings not in the UK but in South Korea. The Guinness World Records have recognised that Doctor Who has broke, accomplished and set many different records. To see a full list, visit the Guinness World Records article on this Wikia.

Even the "gap year" season of 2009-2010, which consisted of only four specials (five if the 2008 Christmas special, The Next Doctor is included), wasn't enough to slow down the train of awards given to Doctor Who. On 20 January 2010 the series won Best Drama and David Tennant won Best Drama Performance at the 2010 National Television Awards.

Feature films
To build upon the success of Dalekmania the series had created in Britain in the 1960s, two feature films were produced (Dr. Who and the Daleks and Daleks' Invasion Earth 2150 A.D.) and released worldwide. Although both were adapted from the William Hartnell television stories The Daleks and The Dalek Invasion of Earth respectively, they feature Peter Cushing as a Human scientist named Dr. Who who invents a TARDIS, and as such are not considered to be canonical.

In 2011 it was announced that a new feature film would be released, to be directed by Harry Potter director David Yates. Although initial news reports suggested that the film would "start from scratch" in terms of continuity, Steven Moffat subsequently clarified that "any Doctor Who movie would be made by the BBC team, star the current TV Doctor and would certainly not be a Hollywood reboot". He later reiterated, "There will not come a time when there's a separate kind of Doctor Who. What was talked about there was that there would be a separate Doctor and a different continuity. Of course it won't. That would be silly. Everyone knows that's silly. The BBC knows that's silly, and is not going to do that."

Other media
Although Doctor Who originated as a television programme, it has become much more than that. Starting with "Dalekmania" in the 1960s, a great deal of merchandise has sprung out of Doctor Who. Some of that merchandise has continued the story of the Doctor's adventures. Over the decades, Doctor Who has appeared on stage, screen, and radio, and in a variety of novels, comics, full-cast audio adventures and webcasts. Beginning in the late 1980s, independent production companies such as BBV Productions and Reeltime Pictures took advantage of a loophole in the BBC's ownership of Doctor Who to licence individual characters and monsters from the series directly from their creators and build original film and audio dramas around them; this reached its height after the original series ended in 1989. Many of these productions involved original cast members from the series. Meanwhile, since 1991, a prolific series of original novels rivalled only by the Star Trek franchise (in terms of quantity) have been published. Many of these productions and novels are highly regarded by some Doctor Who fans. Several of the writers of the 2005 series previously wrote or scripted adventures for the Doctor in other media.

In terms of non-fiction works, Doctor Who ranks among the most intensely chronicled entertainment franchises in history. Since the publication of The Making of Doctor Who in the early 1970s, the number of books detailing the production, personnel, and even philosophy behind Doctor Who has numbered well into three figures. In addition, a growing number of actors connected to the series have published autobiographies (in several cases more than one volume of memoirs), ranging from 1960s-era co-stars such as Anneke Wills and Deborah Watling through to more recent actors such as Billie Piper and John Barrowman.
