That the first ever episode of Doctor Who was transmitted. Forty two years on the series is one of the BBC's most popular shows, having astounded all the fans and pundits and attracted an audience that many television executives claied no longer existed.
Until this year I was arguably part of the final generation, cliched as it may now sound, who had first seen the series with the family as part of Saturday teatime entertainment. I can remember most of the Colin Baker years and despite the myths surrounding them I was never once turned off by supposed heavy levels of violence (which were actually quite tame), excessive continuity (would I have known what that was?!) or guady colours (I never noticed the coat). (However I would like to know just what were these "illegal video levels" on Vengeance on Varos that had to be amended for the VHS and DVD releases and just how they are supposed to have harmed me!) Apart from the removal of some music due to rights, this was the only edit made when that part of the series was released on video so clear the censors didn't have a problem.
The early 1990s were a depressing period for Doctor Who as we waited and waited for news of a new series and had to put up with numerous announcements and confusion. We had the excitement over the announcement of The Dark Dimension, the disappointment of the cancellation of The Dark Dimension (and the later revelation that this was perhaps a mercy killing), all the excitement and speculation about "the Paul McGann TV movie/Enemy Within/the US Telemovie with the Pertwee logo" or whatever it's called this week that ultimately only provided one night of a new show. But the VHS/DVD/tape/CD releases of the old stories, spin-offs and fan activites throughout the years kept everyone going.
And then this year it came true when the series was relaunched. The new series has been little short of fantastic and everyone is talking about it once more. It's no longer considered sad to be a fan of the series. Truly things have come full circle.
