Terror of the Zygons was produced as part of the production schedule for Season 12, but was held for transmission from the end of that season to the beginning of Season 13, to coincide with a move from the new season starting at the beginning of the calendar year, to starting in late summer. Terror of the Zygons was also the last appearance of the Brigadier until Mawdryn Undead in Season 20. The season took a transmission break of two weeks over the Christmas 1975 period, between the broadcasts of The Android Invasion and The Brain of Morbius.
