1974 (releases)


 * 5 January - The Time Warrior Part Four debuted on BBC1.
 * 12 January - Invasion of the Dinosaurs Part One debuted on BBC1. The episode bore the on-screen title Invasion (also sometimes referred to as Invasion Part One) to preserve the cliffhanger of the first episode. This was the first time since the final episode of The Gunfighters aired in May 1966 that an episode carried a title different than that of the complete storyline.
 * 17 January - Target Books followed its successful 1973 reprintings of novelisations from the 1960s with the publications of its first newly commissioned adaptations, Doctor Who and the Auton Invasion by Terrance Dicks, based upon the Third Doctor serial Spearhead from Space, and Doctor Who and the Cave-Monsters by Malcolm Hulke, adapting Doctor Who and the Silurians. Auton Invasion was the first of many Doctor Who novels written by Dicks over the next thirty-plus years and Target continued to novelise Doctor Who adventures for the next twenty years. The practice of giving novelisations titles differing from the broadcast versions continued off-and-on into the 1980s, though it occurred less frequently from the late 1970s.
 * Doctor Who and the Auton Invasion also marked the start of a long and prolific association between Dicks and the world of Doctor Who printed fiction; over the next thirty-five years he wrote not only the lion's share of Target novelisations, but also contributed to most of the later lines of spin-off continuation fiction.
