Season 6

For 6th season of the revived series, see Series 6 (Doctor Who).

The sixth season of Doctor Who ran between 10th August 1968 and 21st June 1969. It featured Patrick Troughton as the Second Doctor.

Overview
Season 6 featured the first UNIT story, The Invasion, which featured the return of Brigadier Lethbridge-Stewart. It also featured the first official appearance of Time Lords and the Doctor's home planet (as yet unidentified by name). (Previously, another Time Lord, the Monk, had appeared, without much elaboration, though the name "Time Lord" first appeared in this season.) It also marked the end of the black-and-white era and the tenure of Patrick Troughton as the Second Doctor. It consisted of 7 serials, and 44 episodes, including two epic-length storylines: the eight episode The Invasion and the 10-episode The War Games. This Season is fortunately more complete than the last 3 seasons, of which only 4 serials exist. 7 episodes from this season are lost, although audio recordings remain for all; as a result, the DVD release of The Invasion uses animation to recreate the two missing episodes from that story.
