 * 4 January - The announcement of Matt Smith as the new Doctor was front page news in many UK newspapers. Since these are Sunday publications, many received international distribution.
 * 8 January - Word reached the Doctor Who production team that a transportation mishap had resulted in the London double-decker bus being shipped to Dubai for use in location filming for Planet of the Dead being heavily damaged. Russell T Davies convened an emergency meeting to discuss how to proceed; the damage was written into the script.
 * 9 January - Big Finish's Bernice Summerfield audio story Glory Days was recorded.
 * 16 January - The website of the UK newspaper The Guardian published a column condemning rumoured plans to film one of the 2009 specials in Dubai, citing the United Arab Emirates' human rights record.

 * 28 January - Media in the UK and United Arab Emirates reported on the damage to the double-decker bus earlier in the month prior to filming the Easter special Planet of the Dead. The BBC News report served as confirmation to earlier rumours that Doctor Who was filming at least part of Planet of the Dead in the Middle Eastern country.

February

 * 5 February - The official trailer for Torchwood: Children of Earth was unveiled at the New York Comic Con and online.
 * 19 February - From Raxacoricofallapatorious with Love was filmed entirely within the 13 Bannerman Road attic set at Upper Boat Studios. (DWMSE 23)

March

 * March - An online version of Doctor Who DVD Files was launched, allowing those who already owned the DVDs, or unable to buy the magazine internationally due to licensing restrictions, access to the printed content of the magazine. The subscription-based site also made the contents of the Doctor Who: Battles in Time series available to international fans.
 * March - The BBC series Tonight's the Night launched a contest for viewers to create their own Doctor Who monster. Following the 28 March deadline, finalists would be chosen to take part in further competition on the series. The winner would appear in a specially written Doctor Who sketch.
 * March - A trailer for the upcoming K9 spinoff series was unveiled at the MIPTV show in Cannes and was later posted online.

 * Mid-March - For the fourth consecutive year, episodes of Doctor Who written by Steven Moffat were nominated for the annual Hugo Award: Silence in the Library/Forest of the Dead. Also nominated was Russell T Davies' episode Turn Left, resulting in fan controversy; his Midnight was expected to be nominated. Competition for the award included episodes of Battlestar Galactica and Lost; this year Doctor Who did not win, and the award went to the made-for-Internet short film Dr. Horrible's Sing-Along Blog.

 * In the weeks following its broadcast of The Next Doctor, the Canadian television network Space confirmed it had obtained the Canadian broadcast rights to the 2009 specials and Series 5, and announced it would air Planet of the Dead in June. This ended speculation over the future of Doctor Who on the CBC, although it was not yet known whether the CBC or related networks would retain broadcast rights to the first four seasons. Up to at least the end of Series 4, the CBC had been a sometimes-credited co-producer of the series; presumably this announcement meant that arrangement had ended.

 * 20 April - The Tonight's the Night skit was filmed.

This was Smith's first performance on camera as the Eleventh Doctor. Russell T Davies met Smith for the first time just prior to shooting. Steven Moffat oversaw the filming of Smith's portion of the regeneration. According to Tennant, he left the studio before Smith filmed his segment, although a photograph of the two together was taken and REF: Doctor Who: The Writer's Tale - The Final Chapter suggested he wasn't quite that rushed.
 * 12 May - Proving some things never change, a survey of parents of young children published in The Telegraph cited Doctor Who as a series blamed for giving children nightmares, with parents surveyed indicating they'd rather see it aired in post-watershed hours.
 * 20 May - David Tennant filmed his final regular-series scenes as the Tenth Doctor for The End of Time, Part Two. Tennant's final scene was a green-screen action shot of him falling through a glass ceiling (the regeneration having been shot earlier).

 * 17 June - The UK tabloid The Sun published a leaked photograph of David Tennant and Timothy Dalton with Dalton in his Time Lord costume, spoiling what was to be a surprise reveal of the return of Gallifrey in The End of Time.

July

 * 20 July - Production began on Series 5 of Doctor Who, with the BBC formally announcing the Doctor's new companion as Amy Pond and unveiling the first photographs of the Eleventh Doctor's costume and revised TARDIS exterior. Media coverage of the first day's filming also revealed a major guest star from Series 4 would return. The episode filmed was later identified as The Time of Angels.
 * 26 July - Doctor Who was officially named the single most successful science fiction TV series by Guinness World Records. The honour was announced at the 2009 San Diego ComicCon.

August

 * 9 August - Steven Moffat's winning streak at the Hugo Awards ended when Silence in the Library/Forest of the Dead was defeated by a Joss Whedon production, Dr. Horrible's Singalong Blog, in the Dramatic Presentation - Short Form category, which Moffat and Doctor Who had dominated since 2006. An examination of the voting results show only about a hundred votes separated Moffat from first place in the final tally. Turn Left by Russell T Davies had also been nominated for the award this year. As Moffat had not written any of the 2009 specials, the earliest he would be eligible again for a Hugo was in 2011.
