I am a long time Doctor Who fan from the classic series. My first memory of it I believe was when I was frightened as a youngster seeing someone with lines across their face. I believe this may have been from The Moonbase. By the time I started watching it regularly in Australia, many episodes were already missing.
At the time of repeats around the time Tom Baker became the Doctor, the collection consisted of Spearhead from Space, Day of the Daleks, The Three Doctors, Carnival of Monsters, The Green Death, and all of Jon Pertwee's last season except for Invasion of the Dinosaurs. In Australia on it's original run and consequent repeats into the 1980's, The Brain of Morbius and The Deadly Assassin were not seen at all. But everything else was and it was perhaps because of this that Tom Baker became my favourite Doctor.
For whatever the reason the ABC in Australia held Tom Baker's last season until they also had Peter Davison's first, and the lot was run together. It of course featured the massive theme switch from the original Delia Derbyshire version to the Peter Howell version. In the 1980's I became an overseas subscriber to the Doctor Who Magazine, and got a letter published in Edition 102 during the argument over the timeline of the Cybermen which was caused by Earthshock. I suspect as a result of using the Tom Baker term "Empirical Poppycock" (from The Armageddon Factor) they delightfully added a candid photo of Tom from The Ark in Space.
I remained a subscriber until it became too expensive to maintain. The series of course ended in 1989 and I missed it terribly. By this time I had seen some of the earlier episodes from William Hartnell and Patrick Troughton, not just on the ABC but also as a member of the Doctor Who Fan Club in Melbourne. It was as a member of this club that I met Katy Manning, and I was later lucky enough at Australia's Whovention to meet Nicholas Courtney. Katy also paid a visit to that.
I'm not as much of a fan of the revived series because it has changed a lot of things that I think it shouldn't have.
