WhoSpy

 was a feature on the Doctor Who website which launched on 20 July 2004. A "spy" on the Doctor Who production team uploaded a new behind-the-scenes photo every weekday throughout the filming of Series 1.

Series 1
WhoSpy initially ran for 36 weeks, finishing on 23 March 2005 and had a total of 176 photos. Following the launch of the "new series" website, it was moved to its "The Making of Doctor Who" section; from the BBC Cult site. During the broadcast of Series 1 the pictures were updated with captions explaining what the photos were of and which episodes they came from.

Series 2
WhoSpy returned for the second series on 5 August 2005, but it stopped abruptly after only 15 weeks and 74 photos on 17 November 2005. The next day the website was redesigned and WhoSpy was completely missing.
