Who is Doctor Who? (tie-in website)

Who is Doctor Who?, also simply titled Doctor Who? and, later, Defending the Earth!, was a website released in March 2005 to coincide with the the 2005 series of Doctor Who, one of several websites created at that time. While the website seems to have been registered by the BBC on 29 June 2004, the earliest archives of content on the site is from 25 March 2005, evidently following the premiere of TV: Rose. On 24 March, the Doctor Who website added a link to the Who is Doctor Who?, visible as "Lies", after the site updated to focus on Rose.

While series one of Doctor Who was being broadcast, each short story was released on the homepage of the site, before being moved to a. For example: "/index1.shtml". The number would change for each story, so PROSE: Dummy Massacre would be under "/index2.shtml", and so on. By 2 April 2006, all of the stories had been filed under a subdirectory, and a new home page was released, and periodically accompanied by short webcasts. Unfortunately, these seem to be no longer accessible.
