Who is Doctor Who? (tie-in website)

Who is Doctor Who?, later titled Defending the Earth!, was a website released on 24 March 2005 to coincide with the the 2005 series of Doctor Who, one of several websites created at that time. On 24 March, the Doctor Who website added a link to Who is Doctor Who?, visible as "Lies", after the site updated to focus on Rose.

Everything on this website is told from an in-universe perspective, as if you were reading the very pages on the in-universe website itself.

In late September 2006, the Defending the Earth! website was nominated for a Y Design Award at the London Design Festival.
