It’s amazing that there are this many Doctor Who stories and we haven’t even got all of them yet - and we know there are even more coming on TV, audio, books and comics. I bloody love Doctor Who and its neverending storytelling.
I think it’ll get over 5000, given how many comics and annual stories there are still to add, but I don’t think it’ll reach 6000 (I have no evidence to back this up though.)
And what’s even more impressive is how a big bulk of that number was released during the 16-year gap between Classic and New Who when there was no new Doctor Who on TV, but it was kept alive through a heavy influx of books, comics and audios (and a magazine devoted to a show that wasn’t on television ).
I think it’s safe to say that if there wasn’t those release after the cancellation, it would have become another old series that got reruns on DAVE. And probably no renewal in '05.
