ii) broadcast anniversaries

30th August 1975: broadcast of the first episode of Terror of the Zygons, launching Season 13. The Doctor, Harry and Sarah, responding to the Brigadier's appeal via space-time telegraph, land in the neighbourhood of Loch Ness which looks strangely like Sussex. Oil rigs are being wrecked in the North Sea; while tending to a survivor, Harry is shot and injured by a servant of the enigmatic Duke of Forgill. As Sarah visits him in hospital, she is grabbed by… a Zygon!!!!!

30th August 1980: broadcast of the first episode of The Leisure Hive, launching Season 18. Poor K9 gets short-circuited on the beach at Brighton; the Doctor and Romana head for the famous pleasure planet, Argolis, but the Doctor, investigating a mysterious chamber, apparently gets torn apart. (Perhaps symbolic of new producer John Nathan-Turner's plans for the show.)

30th August 2002: release of fifth episode of webcast Real Time. Cybermen, viruses and the Time Portal; by this stage I'd lost interest in it but I will give it another go some time.

30 August 2012: release of fourth episode of Pond Life.

30 August 2014: first broadcast of Into the Dalek. The Doctor and Clara are shrunk to explore a Dalek's mind and brain.
