There we go, it's official. Also, the second season of Who premieres on the SciFi channel tonight." From the release: "The series began on 23 November, 1963, and was revived in 2005 after 16 years off the screen. William Hartnell played the original Doctor Who, with Jon Pertwee, Tom Baker and Peter Davison among those following in his footsteps. Christopher Eccleston took up the mantle of the ninth Timelord last year - following the show's relaunch. He was replaced after just one series by David Tennant after Eccleston dropped out. "
