The subscription-based site also made the contents of the Doctor Who: Battles in Time series available to international fans.

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.

Steven Moffat oversaw the filming of Smith's portion of the regeneration.

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.

The ComicCon marked Tennant's first appearance at such an event; he was accompanied by John Barrowman and Russell T Davies.
 * 31 July - The Internet's largest Doctor Who discussion board, the Doctor Who Forum, along with the original Doctor Who News Page, formerly known as Outpost Gallifrey, closed.

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.
