Season 11

Season 11 of Doctor Who ran between 15 December 1973 and 8 June 1974. It starred Jon Pertwee as the Third Doctor.

Overview
It consisted of five serials and twenty-six episodes. It was Jon Pertwee's final season as the Doctor and included, very briefly, the first appearance of Tom Baker as the Fourth Doctor. The Time Warrior, the season opener, introduced Sarah Jane Smith, who would become arguably the most popular of all the Doctor's companions and a frequently featured character in the Doctor Who universe. The same story also, for the first time, named the Doctor's homeworld as Gallifrey. UNIT had also entirely been phased out of the series by this time. Roger Delgado, the first actor who had played the Master, had died, and so the production team did not give the character the dramatic send-off that they had planned in the season finale. The Diamond shaped Doctor Who logo and tunnel effects with Jon Pertwee were introduced, paving the way for the Tom Baker era.

Season 11 was the latest season to be subject to the BBC's then-current policy of junking old episodes. For reasons unknown, only the first episodes of Invasion of the Dinosaurs and Death to the Daleks were erased; copies of both episodes were later reacquired.
