Season 18



The eighteenth season of Doctor Who ran between 30 August 1980 and 21 March 1981. From Full Circle onwards, the season featured a story arc involving E-Space and the return of the Master. It was the last season to feature Tom Baker as the Fourth Doctor; it also saw the departure of Romana and K9. It was the first season produced by John Nathan-Turner, who instituted a number of changes: the stories became darker and more adult in tone, the 1966 Delia Derbyshire arrangement of the "Doctor Who theme" was retired in favour of a new arrangement, and a new series logo was introduced.

Season 18 consisted of seven stories and twenty-eight episodes. It was the last season of the original series to have an autumn-to-spring broadcast schedule and the last to have an autumn start until Season 23. After this season, the number of episodes per season began decreasing. The story State of Decay was originally intended for release in Season 15 under the title The Vampire Mutations.
