Perhaps, but the record DW has is for a single series, not a franchise.
Not that I generally care about this forum, but I just wanted to chime in because this is a great example of lies, damn lies and statistics: rejiggering a definition so that you skew it towards the answer you want.

It's useful to learn to recognize BS like this when it appears in other guises (politics, for instance) where it does a lot more damage.
Obviously, the money made by the whole range of any franchise, including movies, TV, books, video games, DVD sales, action figures, commemorative plates, etc, is the truest gauge of the success of any franchise. It's meaningless to single out TV from all the other media (unless that's part of your statistics-skewing agenda.) Why artificially separate out the story told by
Star Trek's movies from the story told by the TV series?
Star Wars' novels and video games do a lot to advance the whole story (and have done a better job than the movies have lately).
I would guess that
Star Wars has got to be the champion of sci fi franchises. Lucas may be a shitty storyteller, but he sure knows how to squeeze the last dime out of his story.
