I love watching MMA, and I'm fascinated by the lives of the athletes and the business decisions being made around the sport. I'm still waiting for mainstream acceptance of MMA, and here's a start: Georges St. Pierre in a Gatorade commercial. Granted, it's for air in Canada (St. Pierre's home country), but I think this is a good sign. MMA is approaching critical mass. There's a reality show, a video game, corporate sponsors, a million viewers per pay-per-view event, action figures, modest coverage on ESPN, and even CBS tried to get in the game for a bit. We'll see what happens.
