Is MMA (Mixed Martial Arts) a contender? It's been growing steadily in popularity in the prized 18-to-34 male demographic in the last decade, pay-per-view matches are drawing big numbers and the big nod from Hollywood, MMA champs are making the Leno-Letterman talk show rounds and making guest appearances on TV shows. Take that, boxing! And what kind of wimpy sport doesn't let you punch with your feet and choke a guy anyway?
Implications - The younger demographic that was once enthralled by the sport of boxing is now becoming fans of Mixed Martial Arts instead. While this represents a threat to the theatrical boxing industry, I think this is a welcomed switch.
