The more dangerous Vale Tudo style bouts of the early UFCs were made safer with the implementation of additional rules, leading to the popular regulated form of MMA seen today. Originally promoted as a competition with the intention of finding the most effective martial arts for real unarmed combat situations, competitors were pitted against one another with minimal rules. Later, fighters employed multiple martial arts into their style while promoters adopted additional rules aimed at increasing safety for competitors and to promote mainstream acceptance of the sport. The name mixed martial arts was coined by television critic Howard Rosenberg, in 1993, in his review of UFC 1. Following these changes, the sport has seen increased popularity with a pay per view business that rivals boxing and professional wrestling.
UFC 1 used an eight-man tournament format, with the winner receiving $50,000. The tournament featured fights with no weight classes or judges.The two rules, no biting or eye gouging, were to be enforced only by a $1,500 fine. The match only ended by submission, knockout, or the fighter's corner throwing in the towel. Gloves were allowed, as Art Jimmerson showed in his Quarterfinal bout against Royce Gracie, which he fought with one boxing glove. Fights consisted of unlimited 5 minute rounds until a winner was decided.
