It's amazing to say that a television show we love so much is still on our screens, 47 years after the first episode aired. It all started on the 23rd November 1963 with William Hartnell and An Unearthly Child.
I've chosen clips from Blue Peter's coverage of Doctor Who's 10th Anniversary, if only for Peter Purves' (who played Steven Taylor in the Hartnell era) comment in part 2 at 4.36 "It's nice to know that when actors come and actors go, Doctor Who seems to live forever". And you know what? That's absolutely spot on.
So today, I urge you to whack your favourite episode on and enjoy, the best television program ever made.
Happy Birthday Doctor Who!
