This announcement is followed by media reports of Stewart expressing interest in guest starring in a future episode.

April

 * 4 - Exit Wounds is broadcast, ending Torchwood's second series.
 * 5 - Partners in Crime is first broadcast, launching the fourth season of the revived series. Catherine Tate rejoins the series full-time as Donna Noble. Although the news that Billie Piper would return in Series 4 as Rose Tyler had been broken the previous fall by British media, and later confirmed by the BBC both in print and in a trailer shown in British cinemas in which Rose appeared, a cameo appearance by Rose in this episode remains a surprise. This is later attributed to the decision not to include the scene in preview copies sent to media and other parties. Not counting flashbacks, this marks Piper's first appearance in Doctor Who since Doomsday. After the episode is broadcast, the first Series 4 episode of Doctor Who Confidential airs.

 * 3 - The Poison Sky is broadcast. A second cameo by Billie Piper as Rose Tyler occurs; she receives screen credit for her appearance even though she is on screen for less than a second. Russell T. Davies tells Doctor Who Magazine that the decision to include the cameo was a last-minute decision made following the positive response to her cameo in Partners in Crime. To achieve the cameo (and the one later seen in Midnight), unbroadcast footage from an earlier episode (likely Season 2's The Idiot's Lantern) is used. As with Partners in Crime, advance preview copies of this episode omit the scene.
 * 3 - Production of Series 4 officially concludes with the filming of the mini-episode Music of the Spheres.
 * 8 - Pest Control, the first original audio adventure by BBC Audio, is released. Considered a spin-off of the BBC Books Tenth Doctor Adventures line, this marks Donna Noble's debut in such spin-off fiction and is the first officially licenced audio drama not to be produced by Big Finish since the BBC Radio Jon Pertwee radio plays of the mid-1990s.

 * Mid-June - American news media, including CNN, run profiles of Billie Piper, in conjunction with the debut of her series, Secret Diary of a Call Girl in the US. Coincidentally this spike in US coverage coincides with the lead-up to her return to the series in Turn Left, although her involvement in Doctor Who is given only a passing mention. At the same time, it is reported that Christopher Eccleston has been cast as Amelia Earhart's co-pilot in an upcoming film based on the ill-fated aviatrix's life, while John Barrowman makes Canadian headlines when he's named a judge for the talent contest series How Do You Solve a Problem Like Maria? for the CBC.

Reportedly its timeslot will, in some parts of Canada, place it in direct competition with Series 4 of Doctor Who when the CBC begins airing it in September.
 * Late June - Several UK media reports indicate that David Tennant is in negotiations to return to Doctor Who for the 2010 series, but no official announcement is forthcoming (leading to additional speculation in the wake of The Stolen Earth a few weeks later. It is known that he is to appear in the 2008 Christmas special as photos of him shooting the special had leaked to the press months previous.
 * 28 - The Stolen Earth is broadcast. This historic episode marks the first three-way crossover between Doctor Who, Torchwood and The Sarah Jane Adventures. Returning to Doctor Who are John Barrowman, Elisabeth Sladen and Freema Agyeman. The episode receives an Appreciation Index (AI) rating of 91, the highest in the series' history and a feat considered rare if not unprecedented for a mainstream network series.

July

 * Early July - The week between the cliffhanger ending of The Stolen Earth and the broadcast of Journey's End is marked by some of the most intense media attention Doctor Who has ever seen.

Like the previous season finales, the broadcast of Journey's End sparks a frenzy of Internet discussion, both pro and con. The episode features the greatest concentration of active companions (as opposed to illusions and images) in the series' history (not including the non-canonical Dimensions in Time). The episode is viewed by 10.57 million people and becomes the No. 1 program for the week -- the first time this has occurred for any episode in the 45-year history of Doctor Who -- despite competition from the Wimbledon finals; it also repeats the previous week's feat and scores an Appreciation Index figure of 91, again unheard of for both Doctor Who and for a mainstream television production.

Julie Gardner confirms in the article that Tennant has made his decision as to whether he'll be staying on for the 2010 season, but she confirms that he will appear in all of the special episodes scheduled for 2009. Despite this, wildcat Internet rumours persist that Morrissey will replace Tennant as early as the 2008 Christmas special.
 * Mid-July - IDW Publishing issues Agent Provocateur, a graphic novel compilation of the first six-issue storyline of its original Doctor Who monthly comic book, and Doctor Who Classics Vol. 1, collecting the first several issues of reprints originally published by IDW as the monthly title Doctor Who Classics.
