UFC vs. WCL vs. PRIDE

[GT40FIED]

So lately I'm wondering why UFC is so much more popular than other fighting leagues. I caught a WCL (World Combat League...formed by Chuck Norris!) match and thought the format was cooler than UFC. Two fighters fight in one 3 minute round and, assuming you don't get knocked out, you come back and fight in a second round later...tournament style (the way UFC used to be). The PRIDE league also seems better...it's a LOT more brutal since fewer moves are illegal. Plus the fighters all seem to be more single-style based (again, like UFC used to be). That..and as far as I know WLC and PRIDE are only shown on the Versus network, not on Spike TV. The more I watch UFC fights the more it seems like pro wrestling to me. They seem to focus so much on fighter's histories and creating rivalries. Plus very few fighters seem to be true masters of any one style...they know just enough to get by. Sorry, but if you train in boxing, wrestling, kickboxing, and Jiu Jitsu all at once there's a good chance you'll suck at all 4 of them. If you watch old UFC fights you had guys like Royce Gracie fighting...a true master who ruined people's shit like nobody's business. But that figures since Gracie's family created Brazilian Jiu Jitsu. So it begs the question...is it just better marketing that pushes UFC out in front when it seems like an inferior format?
