This weekend, at UFC 157, Ronda Rousey (above, left) and Liz Carmouche (right, on mat) will enter the Octagon in UFC's first-ever female matchup. Clearly the MMA organization is looking to expand its audience. Will this move finally get you to tune in?

Dana White, the founder of UFC, had long said that he would never allow women to fight in UFC matches. Ronda Rousey, the talented—and telegenic—former Olympic judo competitor seems to have changed his mind.

Over the past decade or so, the popularity of mixed martial arts fighting in general, and UFC in particular, has steadily grown. It does solid pay-per-view business and is even featured on network television from time to time. It's possible that by including women on their fight cards, UFC's reach will expand even further.
