 * 31 May - The Sun tabloid reported that Doctor Who would be taken off the air for a year after the conclusion of Series 4 in 2008, except for some specials, with David Tennant leaving midway through the season. The first half of the report proved accurate, the second half less so as Tennant ultimately stayed for all of the specials.

June

July

 * 4 July - The BBC announced in a midnight press release that Catherine Tate would join Doctor Who for Series 4; according to Russell T Davies the announcement was made to preempt an expected story revealing the same by the Sun tabloid the same day. Davies learnt another tabloid The Daily Mail was expected to prematurely break the news of Tennant appearing in Hamlet and the official plan to have a gap year.
 * 7 July - Doctor Who won three trophies at the inaugural Constellation Awards, a Canadian-based honour recognising the best in science fiction and presented during the annual Polaris SF convention. David Tennant won Best Male Performance in a 2006 Science Fiction Television Episode for The Girl in the Fireplace, while Doctor Who itself won the overall Best Science Fiction Television Series category.

September

 * 3 September - The BBC officially announced that Series 5 of Doctor Who would not air until 2010. According to Russell T Davies the announcement was originally to have been made prior to an 11 September press conference by the Royal Shakespeare Company announcing David Tennant's appearance in Hamlet in the fall of 2008, but the release of an RSC brochure in late August required an immediate announcement.

 * 22 October - Piers Wenger was interviewed as a possible replacement for Julie Gardner when she stepped down as producer after the 2009 Specials were filmed.
