2001 (production)

January

 * 15 January - Wikipedia, a free-content online encyclopaedia, was launched, and within a few years became a dominant source for online information, eventually leading to the creation of the Wikia websites which borrowed Wikipedia's format - one of which was the Tardis Wikia, launched in 2005. By the autumn of 2001, articles on the Doctor Who franchise begin to appear on Wikipedia. Although not officially recognised as an influence by its founders, the concept of Wikipedia was often compared to that of The Hitchhiker's Guide to the Galaxy, the repository of all knowledge which was conceived by erstwhile Doctor Who script writer/editor Douglas Adams.
