Doctor Who: Season 4

1966
43 episodes
25m

This season was a season of major changes for Doctor Who, including some that have influenced the series and franchise ever since. Most notably, season 4 saw William Hartnell's First Doctor hand off the baton to Patrick Troughton's Second Doctor in the very first regeneration. When Hartnell announced his plans to leave the series, the show's writers came up with the idea of having the Doctor change his appearance and personality. In 1966, while it was not uncommon for actors to change in ongoing TV and film roles, this was possibly the first time a change in appearance was written into the very nature of the character.

Season 4 of Doctor Who premiered on September 10, 1966 and has 43 episodes, from "The Smugglers (1)" to "The Evil of the Daleks (7)". The last episode aired on July 1, 1967.
