This season was the last to have Barry Letts as producer and Terrance Dicks as script editor, ending the relationship that had gone through the whole of Jon Pertwee's tenure as the Doctor. It saw the introduction of a new logo that would be used nearly throughout the fourth Doctor's era, as well as the new companion Sarah Jane Smith and the alien race, the Sontarans. ==Broadcast==

Episode One of The Time Warrior saw the first appearance of the familiar diamond-shaped Doctor Who logo. This would be used throughout the Third Doctor's final season and almost through the Fourth Doctor's tenure before retiring in part four of The Horns of Nimon (not including the unbroadcast and incomplete serial Shada which would have followed The Horns of Nimon). The entire season was broadcast from 15 December 1973 to 8 June 1974. Season 11 of Doctor Who on BBC1 Wales had very different broadcasts compared to the rest of the UK. Only Part One of The Time Warrior aired on the same day as in the rest of the UK, on Saturday 15 December 1973. On BBC1 Wales, Part Two aired on Monday 24 December 1973, Part Three aired on Tuesday 1 January 1974, and Part Four aired on Tuesday 8 January 1974. Part One of Invasion of the Dinosaurs aired on Tuesday 15 January 1974, and Part Two aired on Sunday 20 January 1974. From then on, Season 11 broadcasts of Doctor Who episodes on BBC1 Wales remained in the Sunday slot, airing one day after the rest of the UK, finishing with Part Six of Planet of the Spiders that aired on Sunday 9 June 1974 on BBC1 Wales. This change of broadcast on BBC1 Wales away from Saturdays for Season 11 of Doctor Who was due to a singing talent show called Gwerin 74 airing in the regular Saturday slot. Like the first 10 seasons, Doctor Who was back in the Saturday slot on BBC1 Wales for Season 12. == Home media ==
