Season 12



The twelfth season of Doctor Who ran between 28 December 1974 and 10 May 1975. It was the first season of the series to feature Tom Baker as the Fourth Doctor. It was also the last Doctor Who season to have a December/January start until the Peter Davison era.

Overview
Season 12 consisted of five serials and twenty episodes and was the shortest season to date. The season was shortened by a decision by the BBC to move Terror of the Zygons, originally intended as the finale, to the start of Season 13 to allow the next season to begin earlier and let Doctor Who better compete against the soon-to-debut Space: 1999.

All the stories in this season were interconnected. Several forming a loose story arc relating to Space Station Nerva. The Cybermen returned to the series for the first time since The Invasion. Genesis of the Daleks, a story which introduced Davros and showed the creation of the Daleks, is one of the most famous of all Doctor Who serials.
