2005 (production)


 * January - The BBC was made aware that Christopher Eccleston was not taking part in a second series of Doctor Who. According to a 4 April press release, the BBC agreed not to announce this to the public. It was later revealed that Russell T Davies had hoped to keep the actor's departure secret until the regeneration in The Parting of the Ways was broadcast.
 * 16 February - The very first edit was made on this wiki, then known as "Tardis Index File", curiously three whole months after the wiki's founding.
 * March - Promotion for the upcoming return of Doctor Who to television entered high gear.
 * 1 March - As early reviews of the new Doctor Who series began to appear, IGN Filmforce reported the American cable broadcaster Sci-Fi Channel, considered the most likely US broadcast home for the series, had chosen not to purchase it. Although there was talk of a related cable network, Universal HD, picking up the series, for the time being United States viewers would not be able to see the new series, with the exception of those close enough to Canada to receive the CBC broadcasts, which was now the North American première of the series.
 * 8 March - Big Finish Productions announced it had agreed to a deal with Paul Cornell allowing the company to continue its range of Bernice Summerfield books and audio CDs for the next few years.
 * 9 March - BBC Radio 4's Today ran a feature on the new series.
 * 12 March - Whether by coincidence or design (as the impending change of lead actor was already known behind the scenes), this week's cover of Radio Times featured yet-to-be-announced Tenth Doctor actor David Tennant in a very Doctor-like pose promoting the mini-series Casanova - right next to a headline promoting the return of Doctor Who. This was the first of many Radio Times covers for Tennant over the next few years.
 * 23 March - Billie Piper was interviewed on The Chris Moyles Show on BBC Radio 1.
 * 25 March - Christopher Eccleston was interviewed on Friday Night with Jonathan Ross.
 * 26 March - Radio Times featured Doctor Who on its cover. With the arrival of the new series, the Radio Times began featuring the series on a more frequent basis.
 * 30 March - The BBC announced production would proceed on a second series and a Christmas Special.
 * 30 March - A publicity branch of the BBC prematurely announced Christopher Eccleston would not return for a second series as the Ninth Doctor, citing his desire to not be typecast. This reason was denied immediately by Eccleston and the BBC ultimately retracted it. Ecceleston later stated he left because he disliked the working environment. In his 2008 book The Writer's Tale, Russell T Davies confirmed that Eccleston's departure was intended to be kept secret until the final moments of The Parting of the Ways.
 * 4 April - The BBC retracted part of its 30th March announcement of the departure of Christopher Eccleston, indicating it released the information with incorrect attribution and without the actor's consent.
 * 16 April - David Tennant was officially announced as the Tenth Doctor. At this time Tennant was best known for playing the title role in Casanova, a BBC miniseries written and produced by Russell T Davies. He had also recently filmed a role in Harry Potter and the Goblet of Fire, which was released to theatres the same day his first solo performance as the Doctor was broadcast.
 * May - The Canadian Broadcasting Corporation in Canada began airing the new series, the first time the CBC had aired Doctor Who since the mid-1960s. For the CBC broadcasts, Christopher Eccleston videotaped special introductions and promotions for a contest sponsored by TV Guide, the first prize being a trip to London to visit the set of Doctor Who. These broadcasts were promoted as the North American debut of the series, as no other broadcaster on the continent had yet picked up the revived series.
 * 11 June - Christopher Eccleston was interviewed by BBC Radio.
 * 18 June - Post-production was completed for The Christmas Invasion.
 * Following the conclusion of the 2005 Doctor Who series, the BBC announced it had commissioned the franchise's first spin-off series, Torchwood, to debut in 2006 and star John Barrowman reprising his role of Jack Harkness.
 * 25 July - The BBC announced that Elisabeth Sladen would return to the role of Sarah Jane Smith for an upcoming episode of the revived Doctor Who's second series.
