In the late-1980s, a VHS tape circulated through the martial arts underground. The grainy video, Gracies in Action, showed a slim Brazilian fighter in a traditional gi fighting a boxer, a wrestler, and finally a karate master. Art Davie saw the tape, and with Rorion Gracie, devised War of the Worlds, a combat tournament featuring fighters from every discipline. In 1993, the Ultimate Fighting Championship debuted in Denver, Colorado, and 86,000 home viewers paid to watch. Since then, under the leadership of UFC president Dana White, the popularity of MMA has skyrocketed.
