I'd prefer UFC try and go for a wider audience by getting on one of the major networks (FOX, ABC, NBC, CBS). That would be a major win for them.
Part of the reason boxing has declined in popularity is all the good fights are on pay tv (HBO, Showtime, PPVs). People use to be able to catch Ali fights for free on the radio or TV. It's no wonder boxing was more popular back then. Kids don't grow up watching it so they don't who these guys are anymore.
If you really wanna grow MMA as a sport, get it on free TV. UFC has done well now on cable and PPVs, but it could be even bigger.
