This is 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 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 DW: 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, while some UK media report that Tennant has signed an agreement to stay with the series through Series 5 in 2010.
 * 12 - Doctor Who sweeps the television categories at the second annual Constellation Awards, a Canadian award presented as part of the Polaris science fiction convention.

The announcement sparks a period of intense fan and media speculation as to who will be chosen to portray the Eleventh Doctor.

 * 12 - Broadcast of DW: Journey's End on the CBC in Canada, concluding its broadcasts of Series 4. The network chooses to extensively edit the episode down to approximately 44 minutes in order to fit a standard 60-minute time slot, with commercials, raising the ire of many Canadian fans who afterward flood the CBC's website with complaints. The season ends with no plans by the CBC to broadcast DW: Voyage of the Damned or DW: The Next Doctor (the CBC ultimately loses 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 attends a secret photo shoot; so secret, in fact, that the hairstylist and photographer are not informed what it's for.

 * 25 - DW: The Next Doctor, the fourth Doctor Who Christmas special, is first broadcast. This is 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 is scheduled to return to a full 13-week season in 2010. This is the first story since DW: The Deadly Assassin in which the Doctor does not share an adventure with a clearly defined companion (even in a one-off manner). The title of the first special, DW: Planet of the Dead, is unveiled during the closing credits. The episode is notable for including a sequence in which the nine actors who played the Doctor prior to Tennant are shown; in some cases, such as William Hartnell and Patrick Troughton, this marks the first on-screen appearance of their Doctors in more than two decades.
 * An edition of Doctor Who Confidential follows the broadcast.
