2008

January

 * Owen Harper went undercover to prevent the Weevils from being abducted by humans. (TW: Combat)

Early February

 * Jack Harkness and Toshiko Sato were transported back in time to The Ritz in 1941. Owen used the Rift Manipulator to bring them back, opening the Rift. By this point, Harold Saxon's campaign for election was underway as "Vote Saxon" signs were visible in Cardiff. (TW: Captain Jack Harkness)
 * As the Cardiff rift opened, the Rift quickly pulled beings through it, at a steadier pace. Visions started appearing to the Torchwood Three team, and Rhys Williams was murdered. As a result, the Rift was closed, undoing the damage, but Abaddon was unleashed, wiping out hundreds of people. Jack killed Abaddon with an overflow of life energy, which left Jack dead for days. (TW: End of Days) Shortly after being restored to life, Jack heard the sound of the Doctor's TARDIS, and re-joined the Doctor as the TARDIS hurtled toward the year 100,000,000,000,000. (TW: End of Days, Utopia)
 * Meanwhile, Jack was declared missing by his Torchwood teammates, and Gwen Cooper took charge of the group. Subsequently, Ianto Jones began taking a more active role in field assignments. (TW: Kiss Kiss, Bang Bang)

March

 * The Eleventh Doctor met Amy Pond in Leadworth after twelve years of waiting. A Multi-form named Prisoner Zero, who had escaped through the crack in Amy's wall at that time, attacked. The Atraxi arrived, threatening the destruction of Earth if Prisoner Zero did not surrender. The Doctor created a computer virus for the Atraxi to track back to its source in Leadworth (spread by Jeff). The Doctor also transmitted Prisoner Zero's disguises to the Atraxi so it couldn't hide in the bodies it had been disguised as. It then took the form of Amy; the Doctor made Amy think of Prisoner Zero's original form. Now in plain sight, Prisoner Zero was captured by the Atraxi and left. The Doctor took a test drive of his refurbished TARDIS, only returning two years later. (DW: The Eleventh Hour)

Spring or Summer

 * Maria and Alan Jackson moved into 36 Bannerman Road, Ealing, the house opposite Sarah Jane Smith's. The Bane used a 'natural ingredient' hidden in their Bubble Shock! drink to enslave humanity. Sarah Jane and Maria went to the Bubble Shock! factory and stoletheir human archetype. The archetype used a communication device from a Star Poet to destroy the Bane Mother and freed the mind-controlled people. One Bane, Mrs Wormwood, escaped from the exploding factory. Sarah Jane adopted the Archetype and named him Luke. (SJA: Invasion of the Bane)
 * The Slitheen family killed overweight teachers and created technology labs for their energy draining machine to cool the Sun, intending to sell the destroyed Earth. In the testing phases, the Earth briefly experienced a worldwide power outage. Luke unwittingly gave the code that would make the machine work properly to the Slitheen. Clyde Langer joined Luke, Maria and Sarah Jane in investigating the schools, fighting the Slitheen off with vinegar. When tried out on the Sun, the Slitheen's fixed machine overloaded and was destroyed, with a lone survivor teleporting away. Sarah Jane used her supercomputer Mr Smith, to orchestrate a cover-up that suggested the darkening of the sun and the power outage were caused by a sudden, but temporary, shift in Earth's magnetic field. (SJA: Revenge of the Slitheen)
 * Royal Hope Hospital was teleported to the Moon with the Tenth Doctor and Martha Jones inside, for the Judoon to search for a murderer. Identified as non-human, the Doctor escaped the Judoon after he was mistaken for the murderer. The Doctor's blood was later sucked by Florence Finnegan (the murderer). Martha revived him. The Judoon positively identified and executed Finnegan. The Doctor stopped a supercharged MRI machine from wiping out Earth. The hospital was returned and Martha joined the Doctor in the TARDIS. Mr. Saxon continued his campaign for British Prime Minister. He was given high support after the hospital's disappearance, then reappearance. (DW: Smith and Jones; The Sound of Drums, et al, establishes this occurs only a few days before the election.)
 * Richard Lazarus unveiled an age-reversing machine which initially de-aged him, then transformed him into a possible evolutionary branch of humanity, latent in his DNA, becoming a monster in doing so. The Tenth Doctor killed Lazarus. (DW: The Lazarus Experiment)
 * Election Day began and Harold Saxon was voted British Prime Minister. A mysterious woman surveilled Francine Jones' phone, as she knew Francine's daughter Martha was in contact with Saxon's enemy, the Doctor. (DW: 42 / The Sound of Drums; Note: This is likely to replace whoever was appointed interim PM after the ouster of Harriet Jones per DW: The Stolen Earth)
 * At, or around this date, Saxon sent Torchwood Three on a "wild goose chase" mission away from Great Britain (DW: The Sound of Drums) to the Himalayas where they were told (apparently by 'the highest authority') that another Rift had been discovered halfway up K2. When they got there, however, they foundt it a trap. They were almost killed in an avalanche while distracted by a 'Jack-in-a-box' (http://www.bbc.co.uk/torchwood/sites/arg/pages/episodes.shtml?folder=tw_case_ep01&tab=2)
 * The Tenth Doctor, Jack and Martha returned from 100,000,000,000,000, went on the run as fugitives declared by Harold Saxon, in fact the Master. The Master announced on television that humanity was to make first contact with the Toclafane. President Winters stepped in, allowing UNIT to take control. The Doctor, Martha and Jack snuck aboard the Valiant; the Toclafane murdered President Winters. The Master, seeing through the Doctor and his companions' perception filters, heavily aged the Doctor and captured him and Jack. (DW: The Sound of Drums)
 * The Year That Never Was began; the Master built a Time Lord Empire and Martha Jones travelled the world executing the Doctor's plan. Ultimately, the year was negated and the clock reset to just after the Master killed Winters. Lucy Saxon killed the Master. Martha Jones and Jack returned home and left the Doctor on his own. (DW: Last of the Time Lords) Lucy was subsequently imprisoned; unknown to her, a group of Saxon's followers retrieve a ring from Saxon's funeral pyre and begin preparations for restoring the Master to life the following year. (DW: The End of Time, Part One)
 * Captain Jack returned to Torchwood Three, and met John Hart, who was sent on a wild goose chase to find an Arcadian diamond. In finding the apparent keys to its location, he was implanted with a bomb attached to his DNA. The Torchwood Three team disposed of the bomb and sent John through the Rift. John told Jack he had found Gray. (TW: Kiss Kiss, Bang Bang)

 * Teenagers went missing after playing Combat 3000. Luke Smith and Clyde Langer were among them. Sarah Jane Smith discovered they were being teleported by an alien named Kudlak who has taken them to a war ship to fight in an alien war. After Luke discovered the war had ended ten years earlier, Kudlak returned the children and searched for the children he had sent to distant worlds. (SJA: Warriors of Kudlak)
 * Rhys Williams discovered the truth about Gwen Cooper's job when he was caught up in Torchwood Three's investigation of a Space Whale. Owen euthanised the whale. (TW: Meat)
 * A being which used the name "Adam Smith" escaped from the Void and lived parasitically by altering and inserting himself into others' memories. Adam was drawn to the unique memories of Torchood Three and made them believe he was a long-time member of their team and Toshiko Sato's lover. Ianto Jones and Captain Jack Harkness exposed Adam after Ianto found no reference to him in his written diaries, and the team banished himto the Void by retconning themselves to forget the whole incident. (TW: Adam)
 * Sarah Jane Smith was given a puzzle box by a Verron soothsayer, with instructions to give it to someone she trusted. The next week she gave it to Maria Jackson. The Trickster retroactively wiped Sarah Jane out of existence, but reality was restored with help from Maria Jackson, Alan Jackson and Andrea Yates, the woman who had caused all this. Mr Smith pushed a meteorite headed for Earth out of the way. (SJA: Whatever Happened to Sarah Jane?)
 * A few days after the incident with the Trickster and five months after the thwarted Bane invasion, Mr Smith, and the Slitheen tried to uses Luke Smith's telekinetic abilities via a MITRE headset to collide the Moon with Earth, freeing his Xylok brothers.

 * Dr. Martha Jones arrived in Cardiff on the trail of the the Pharm, who had been experimenting on humans with a drug called Reset. Martha was temporarily assigned to Torchwood Three. The Pharm was shut down, but Dr. Owen Harper was shot and killed by Aaron Copley. (TW: Reset)
 * Before Martha Jones could conduct an autopsy on Owen Harper, he was revived by Jack Harkness using the second resurrection gauntlet. For reasons unknown, Harper continued to live past the standard two and a half minute revival time. He was briefly possessed by Duroc, the embodiment of Death. Deaths occurred at a Cardiff hospital as a result of Duroc's manifestation. Owen defeated Duroc, not having any life energy for Duroc to steal. (TW: Dead Man Walking)

December

 * mid-December - The Aurelia Festival was held in Stockbridge. The Tenth Doctor and new companion Majenta Pryce arrived to find themselves involved in an adventure with Maxwell Edison. (DWM: The Stockbridge Child)
 * 24-25 - The Tenth Doctor, after repairing a hole in space-time with the help of his fifth incarnation (DW: Time Crash), found himself aboard a space-faring replica of the Titanic in orbit around Earth. Some of the passengers (including the waitress Astrid Peth) briefly landed in the middle of London. As the two previous Christmases had been disrupted by the arrival of alien spacecraft over London (DW: The Christmas Invasion and DW: The Runaway Bride), most residents of the city had left for the season. Those choosing to remain in the city included Queen Elizabeth II and Wilfred Mott, grandfather of Donna Noble. A series of meteorites were deliberately allowed to collide with the deshielded Titanic, causing the ship and its nuclear storm drive to hurtle towards Earth. Most of the survivors of this collision were killed by the Heavenly Host. After the Doctor used the Host's security protocol to find the man in charge, Max Capricorn, Astrid followed, killing Capicorn, but dying with him. The Doctor piloted the Titanic to safety, just missing Buckingham Palace. The only survivors were Midshipman Alonso Frame, Rickston Slade, the Doctor and Mr Copper. Astrid was partially revived as starlight. Mr Copper, having realised that he has had money for the first time in his life, retired to Earth. (DW: Voyage of the Damned) Donna Noble would dismiss the near-miss by the Titanic as a hoax. (DW: Partners in Crime)

Dates Unknown

 * Following her encounter with the Tenth Doctor and the Empress of the Racnoss, Donna Noble attempted to improve her life by travelling to Egypt. Afterwards, experiencing regret at turning down the Doctor's invitation to travel with him, Donna began investigating unusual events in hopes of encountering the Doctor doing the same. Her investigations led to her learning about the disappearance of bees and Adipose Industries, which eventually led to her reuniting with the Doctor in 2009. (DW: Partners in Crime)
 * During an unchronicled adventure in London with Martha Jones, the Doctor met Sally Sparrow, who gave him information he would need to escape when the Weeping Angels sent him back to 1969. After this, Sally began to open up to Larry Nightingale. (DW: Blink)

Andrea Yates' World

As a result, the Earth was susceptible to the meteorite strike, fuelling chaos the Trickster could feed on. Maria was erased by Krislok. Alan, who remembered Maria when no-one else did thanks to holding the puzzle box, confronted Andrea Yates about Sarah Jane. Andrea revoked her deal with the Trickster, returning the timeline to normal. (SJA: Whatever Happened to Sarah Jane?)

Behind the scenes

 * 4 - WC: The Baktek Illusion was uploaded, concluding the BBC Writers' Comics special series.
 * 5 - DW: Journey's End was first broadcast, bringing to a close the fourth series of the revived Doctor Who. It was the last episode to be produced by Phil Collinson, the first of the revived series' original producers to depart. The episode featured the one-time returns of Noel Clarke, Camille Coduri and K9 to the series; Catherine Tate left the series as a regular with this episode. This was the last regular weekly episode of Doctor Who scheduled until Series 5 in 2010. Like the previous season finales, the broadcast of Journey's End sparked a frenzy of Internet discussion, both pro and con. The episode featured the greatest concentration of active companions (as opposed to illusions and images) in the series' history (not including the non-canonical DW: Dimensions in Time). The episode was viewed by 10.57 million people and became the No. 1 program for the week -- the first time this had occurred for any episode in the forty-five-year history of Doctor Who -- despite competition from the Wimbledon finals; it also repeated the previous week's feat and scored an Appreciation Index figure of 91, again unheard of for both Doctor Who and for a mainstream television production.. The episode concluded with a teaser for the 2008 Christmas special, at the time of broadcast left untitled but later announced as DW: The Next Doctor. As K9 did not appear in Series 2 of The Sarah Jane Adventures, this marked his final appearance until the post-season mini-episode SJA: From Raxacoricofallapatorius With Love aired in March 2009.
 * Afterwards, the final Series 4 episode of Doctor Who Confidential was broadcast.
 * 6 - DW: Partners in Crime was broadcast on ABC in Australia.

 * 8 - The Bred for War DVD box set (DW: The Time Warrior, The Sontaran Experiment, The Invasion of Time, The Two Doctors) was released in Region 4.
 * 11 - The Telegraph reported on rumours of David Tennant stepping down from the role of the Doctor, with David Morrissey, John Simm, and Robert Carlyle cited as the book-maker's favourites to replace him, despite Morrissey scheduled to guest star in the 2008 Christmas special and Simm having already played The Master in Season 3. Julie Gardner confirmed in the article that Tennant had made his decision as to whether he would stay on for the 2010 season, but she confirmed he would appear in all of the special episodes scheduled for 2009. Despite this, wildcat Internet rumours persisted that Morrissey would replace Tennant as early as the 2008 Christmas special, while some UK media reported Tennant had signed an agreement to stay with the series through Series 5 in 2010.
 * 12 - Doctor Who swept the television categories at the second annual Constellation Awards, a Canadian award presented as part of the Polaris science fiction convention. David Tennant won for best Male Performance in a Science Fiction Television episode for his work on the two-parter DW : Human Nature/The Family of Blood; Carey Mulligan won the female equivalent for DW: Blink; and the series itself won for Best Science Fiction Television Series of 2007. Doctor Who was eligible for these awards thanks to its co-production arrangement with the CBC.

The issue also included a second surprise: when the polybag was removed, all text on the front cover (except around the UPC symbol) was revealed to be "BAD WOLF", including the title banner for the magazine itself! This was a tie-in with the ending of DW: Turn Left.
 * Publication of DWC: Doctor Who Classics Volume 1, a graphic novel-style release reprinting the first few issues of DWC: Doctor Who Classics by IDW Publishing.
 * 27 - The first Doctor Who Proms concert was held at Royal Albert Hall in London, featuring music from Doctor Who. An interactive mini-episode, DW: Music of the Spheres, was shown as part of this event, which was initially broadcast on BBC Radio. The concert was hosted by Freema Agyeman, with Catherine Tate appearing to introduce a segment, as well. Singer Tim Phillips, who performed "Song for Ten" in DW: The Christmas Invasion, performed the extended version of the song introduced on the Series 1 &amp; 2 soundtrack CD. Davros, the Graske and other monsters made cameo appearances as well. As a tribute to the BBC Radiophonic Workshop and Delia Derbyshire, Music of the Spheres ended with the original 1963 arrangement of the "Doctor Who theme". The BBC later announced that an edited version of the broadcast -- including Music of the Spheres -- would air on 1 January 2009.

 * In multiple interviews conducted in March and April of 2010, Matt Smith indicated he had been chosen to play the Eleventh Doctor "three months" before the official announcement was made in early January 2009.

Tennant made the announcement on live TV when he accepted the National Television Award for Outstanding Drama Performance. The series also won Most Popular Drama. Tennant's announcement was made hours after The Guardian broke the news first on its website. As the winner of the NTA was not previously known, it was uncertain whether Tennant would be able to deliver his announcement on the air. The announcement was timed to occur during an intermission in his performance of Hamlet, and Tennant pre-recorded a version of it in the event the live transmission broke down. Earlier in the day, Russell T Davies and Benjamin Cook appeared on a TV broadcast discussing their book, REF: Doctor Who: The Writer's Tale, and managed to avoid discussing the yet-to-be-made announcement. (REF: Doctor Who: The Writer's Tale - The Final Chapter)
 * Tennant's announcement sparked a period of intense fan and media speculation as to who would be chosen to portray the Eleventh Doctor. Speculated names ranged from well-known to obscure actors, and also included caucasian and black candidates, as well as a revival of speculation about a female actor being cast, an idea that dated back to the 1970s.

As The Infinite Quest was never broadcast in North America, this marked the first time that a Doctor Who serial has been released to DVD in North America without first having been broadcast there, discounting prior releases of incomplete and restored serials from the 1960s. Series 4 was released in Canada even though the CBC was only midway through its broadcast of the season.
 * 23 - Forty-Fifth anniversary of the first broadcast of Doctor Who.
 * 24 - SJA: The Temptation of Sarah Jane Smith part 2 was first broadcast.

 * BFA: The Raincloud Man was first released.
 * CC: The Darkening Eye was first released.
 * ST: Short Trips: Christmas Around the World was first published.

 * According to BBC News, a "long-standing back injury" forced David Tennant to miss several performances of Hamlet at London's Novello Theatre. Ultimately, Tennant underwent back surgery.
 * 10 - Although the announcement wasn't made for several weeks, Russell T Davies was informed that Matt Smith has been cast as the Eleventh Doctor. (REF: Doctor Who: The Writer's Tale - The Final Chapter)
 * 12 - Broadcast of DW: Journey's End on the CBC in Canada, concluding its broadcasts of Series 4. The network chose to air an extensively edited version of the episode, cut down to approximately forty-four minutes to fit a standard sixty-minute time slot, with commercials, raising the ire of many Canadian fans who afterward flooded the CBC's website with complaints. The season ended with no plans by the CBC to broadcast DW: Voyage of the Damned or DW: The Next Doctor (the CBC ultimately lost the rights to air The Next Doctor and the remaining 2009 Specials, plus Series 5, in the spring of 2009).
 * 24 - A little-known actor named Matt Smith attended a secret photo shoot; so secret, in fact, that the hairstylist and photographer were not informed what it was for. Later, an image of the TARDIS would be digitally added to the photos, which would be issued on 3 January 2009 to announce Smith as the actor to play the eleventh Doctor.
 * 25 - DW: The Next Doctor, the fourth Doctor Who Christmas special, was first broadcast. This was considered the last episode of Series 4 before four special episodes planned over the next year in lieu of a full season of Doctor Who, which was scheduled to return to a full thirteen-week season in 2010. This was the first story since DW: The Deadly Assassin in which the Doctor did not share an adventure with a clearly defined companion even in a one-off manner, as the story twisted conventions by placing the Doctor in the companion role. The title of the first special, DW: Planet of the Dead, was unveiled during the closing credits. The episode was notable for including a sequence in which the nine actors who played the Doctor prior to Tennant were shown; in some cases, such as William Hartnell and Patrick Troughton, this marked the first on-screen appearance of their Doctors in more than two decades, and it was the first unambiguous confirmation that the revived series counted Paul McGann's Eighth Doctor in its continuity.
 * An edition of Doctor Who Confidential followed the broadcast.
 * 29 - Publication of DWC: Doctor Who Classics Volume 2, a graphic novel-style release reprinting issues of DWC: Doctor Who Classics by IDW Publishing.
