If you are asking about currently ongoing, then there is also Natural 20 [http://www.escapistmagazine.com/videos/view/nat-20] and GoodBadFlicks [http://www.escapistmagazine.com/videos/view/good-bad-flicks]. If you also want to know which one of their currently ongoing series are exclusive, then it seems like GoodBadFlicks [https://www.youtube.com/user/trachenburg] is not, the other three are.SolidState said:
If you want to know in general, not just current shows, then I don't really know. There are, of course, the old videos uploaded but whether you count that as "having" is a different manner - I'd personally take that to mean in some exclusive fashion and I am not aware of how the rights there are - I know that stuff like LoadingReadyRun's Unskippable and ENN were produced for the Escapist and it seems like they are staying their property. From what I've heard, at least. But I don't know about all the series, ever.
