Unknown dates

 * Labour action forced production to be halted on the six-part serial HOMEVID: Shada. Ultimately, it was decided to abandon the serial, which signalled a premature end for the 1979-80 season with The Horns of Nimon.
 * REF: Terry Nation's Dalek Special was first published. This Target Books trade paperback release, edited by Terrance Dicks, included the novella Daleks: The Secret Invasion, written by Terry Nation, which was the first piece of original Doctor Who-related fiction to be published by Target, as well as Nation's only fiction writing for the company. As the book included a synopsis of Destiny of the Daleks, it can be surmised it was probably published after that serial was broadcast.
