The biggest name in mixed martial arts, UFC is a multimillion-dollar business that fills arenas, broadcasts events on pay-per-view and has deals with cable networks like Spike TV. The sport, which combines jiujitsu, judo, karate, boxing, kickboxing and wrestling, has put off some critics with its ferocity, including such tactics as kicks to the head.
