<passage>:
Fight Club , a movie about a fictional organization of men who strip down and beat each other to pulp, has provoked more than its share of media hand-wringing, particularly diatribes about Hollywood's infatuation with violence and Faludi-esque ruminations about the emasculated American male. Fight Club , however, has not sparked an iota of interest in a real organization of men who strip down and beat each other to pulp: the Ultimate Fighting Championship. UFC's flameout from national sensation to total irrelevance is a tragedy of American sports, a cautionary tale of prudishness, heavy-handed politics, and cultural myopia. UFC began in 1993 as a locker-room fantasy. What would happen if a kickboxer fought a wrestler? A karate champion fought a sumo champion? Promoters built an octagonal chain-link cage, invited eight top martial artists, and set them loose in no-holds-barred, bare-knuckles fights. "There are no rules!" bragged an early press release. Contestants would fight till "knockout, submission, doctor's intervention, or death." UFC allowed, even promoted, all notions of bad sportsmanship: kicking a man when he's down, hitting him in the groin, choking. Four-hundred-pound men were sent into the Octagon to maul guys half their size. Only biting and eye-gouging were forbidden. The gimmick entranced thousands of people (well, men). What happens when a 620-pound sumo champion fights a 200-pound kickboxer? Answer: The kickboxer knocks him silly in 35 seconds. They tuned in for bloodshed--"the damage," as fans like to call it. UFC fights could be horrifying. Tank Abbott, an ill-tempered, 270-pound street fighter, knocks out hapless opponent John Matua in 15 seconds. Then, before the ref can intervene, Abbott belts the unconscious Matua in the head, sending him into a fit, limbs quivering uncontrollably, blood spurting from his mouth. Abbott, naturally, became a cult hero and won a guest spot on Friends . (Matua walked out of the ring.) Soon, UFC was selling out huge arenas and drawing 300,000 pay-per-view subscribers for its quarterly competitions. But a subtle sport was emerging from the gimmicks and carnage. My passion for ultimate fighting (which is also called "extreme" or "no-holds-barred" fighting) began when I saw the finals of UFC IV. Royce Gracie, a 180-pound Brazilian jujitsu specialist, was matched against a 275-pound beast named Dan Severn, one of the top heavyweight wrestlers in the world and a national champion many times over. In 30 seconds, Severn had grabbed Gracie, flung him to the canvas, and mounted him. For the next 15 minutes, Severn pummeled and elbowed and head-butted the smaller man. Gracie's face grew drawn, and he squirmed wildly to avoid Severn's bombardment. Then, all of sudden, Gracie, still lying on his back, saw an opening, wrapped his arms and legs around Severn like a python and choked the giant into submission. UFC's caged matches revolutionized the idea of fighting. Nursed on boxing and Hollywood, Americans imagine fights as choreography, a dance of elegant combinations, roundhouse kicks, clean knockouts. The UFC punctured this. Boxers floundered. Experts in striking martial arts such as karate and tae kwon do, who fancied themselves the world's greatest fighters, found themselves pretzeled by jujitsu masters, who pulled them to the ground and slowly choked or leg-locked them. "UFC immediately debunked a lot of myths of fighting, of boxing, karate, kung fu. It showed the reality of what works in an actual fight," says Dave Meltzer, editor of Wrestling Observer . Instead of being carnivals of gore, UFC fights looked strangely like ... sex. Almost all fights ended on the ground, one man mounting the other in missionary position, the pair of them wiggling mysteriously along the canvas for five, 10, even 30 minutes. There were few spectacular knockouts. The referee--yes, there was always a referee--stopped many bouts, and in most others, fighters "tapped out," surrendering to mild-looking but agonizing chokes and joint locks. It was not barbarism. It was science. The UFC spawned a new breed of "mixed martial artists." World-class wrestlers learned to kickbox. Champion kickboxers learned to grapple. (The karate experts learned to stay home.) They became, without doubt, the best fighters in the world. (Click for more about the fighters.) Mike Tyson wouldn't last 30 seconds in an ultimate fighting match. When Olympic gold medal wrestler Kevin Jackson came to the UFC, a fighter named Frank Shamrock KO'd him with a submission hold in 16 seconds. Ultimate fighting schools began sprouting up all over the country, replacing the stylized gestures of the Eastern martial arts with techniques that actually work. UFC fell victim to cultural determinism about what a fight is. In countries such as Brazil and Japan, where no-holds-barred fighting has a long history, it is popular and uncontroversial. But Americans adhere to the Marquis of Queensbury rules. A fight consists of an exchange of upper-body blows that halts when one fighter falls. Any blood sport can be barbaric, whether it's boxing or wrestling or ultimate fighting. It is impossible to draw a bright line between ultimate fighting and boxing. If anything, ultimate fighting is safer and less cruel than America's blood sport. For example, critics pilloried ultimate fighting because competitors fought with bare knuckles: To a nation accustomed to boxing gloves, this seemed revolting, an invitation to brain damage. But it's just the reverse: The purpose of boxing gloves is not to cushion the head but to shield the knuckles. Without gloves, a boxer would break his hands after a couple of punches to the skull. That's why ultimate fighters won't throw multiple skull punches. As a result, they avoid the concussive head wounds that kill boxers--and the long-term neurological damage that cripples them. Similarly, the chain-link fence surrounding the octagon looks grotesque. Critics have demanded that UFC install ropes instead. But ropes are a major cause of death and injury in boxing: Fighters hyperextend their necks when they are punched against the ropes, because nothing stops their heads from snapping back. The chain-link fence prevents hyperextension. and 2) the same cable outfits carried boxing matches, R and NC-17 movies, and professional wrestling shows far more violent than UFC. The UFC's "addressable audience"--the potential number of PPV subscribers--shrank from 35 million at its peak to 7.5 million today. "Sports fans want to grow with the sport," says former UFC fighter David Beneteau. "They want to recognize the athletes. They want to see the same fighters come back. When you compare UFC now to what it was, the fighters are not the same, the rules are not the same. The fans have no story to follow."
