This is not counting the Doctor Who spin-offs like Torchwood and the Sarah Jane stuff, but I'm not sure that those would put it over the top anyway, or that they should really be counted.
Certainly wouldn't put it over the top (adds about 52 hours) but I don't see why they wouldn't be counted. Same franchise, with crossovers.
Comic strip totals might be interesting to compare, since I guess 2 or 3 Trek's must have been running at the same time. Doctor has had a strip in some form since 1964. As well as longest running magazine based on a TV programme.
How many original Trek Novels? At least 300 for Doctor Who in print, not counting 156 novelistions, or original books for audio.
And that's without counting audio drama.
I'm surprised Trek's never got very far with audio drama.
