The concept of mixed martial arts actually dates to the ancient Greek Olympics of 648 B.C. when it was called Pankration ("all powers") and it is like a combination of the four modern Olympic sports of wrestling, judo, boxing, and taekwando. (Many Olympic medalists in wrestling and judo have also successfully competed in MMA, including U.S. Olympic wrestling gold medalist Rulon Gardner.) It is currently very popular in Japan and Brazil, as well as the U.S, Holland, and Russia, though there have recently been MMA events in dozens of countries including Canada, Mexico, the UK, Ireland, Denmark, Finland, Greece, Italy, Israel, Kuwait, Australia, China, South Korea, and Thailand. MMA competitors come from all these countries and many more.
In the U.S., it's fully sanctioned by the Nevada & New Jersey State Athletic Commissions (it's sanctioned in other states too, but UFC events are usually in Las Vegas or Atlantic City) and there are actually quite a few rules to protect the safety of the fighters and prohibit potentially dangerous strikes such as headbutts, groin strikes and kicks to the head of a downed opponent. Competitors weigh in before the events and must compete in their own weight class. They usually compete in fight shorts or grappling shorts, but they may also wear a judo/karate gi or other traditional attire of their martial art. They also wear protective equipment such as mouthpieces, cups, and lightweight grappling gloves to protect their hands from injury when striking (boxing gloves & hand wraps are actually much more dangerous because they are much heavier, creating a higher likelihood of serious injury due to repeated blows to the head) while still enabling them to grab onto their opponent for grappling techniques. The reason many MMA fights are held in a chain-link-fence type cage (the fence is rubberized to prevent scratching or cuts) is because grappling in a ring can be dangerous - the fighters can easily slip through the ropes and fall onto the hard surface below. Because of these safety precautions and because the close quarters grappling aspect of the sport reduces the frequency of high impact collisions, there are many fewer serious injuries in MMA than in other contact sports such as boxing, football, rugby, and hockey.
MMA is exciting in part because there are so many ways to win - takedowns, throws, punching, kicking, knees, elbow strikes, submission holds (arm locks, leg locks, chokes) - which makes the fights as much of a mental chess match as a physical contest. Fighters may honorably end a fight at any time by "tapping out" to signal their surrender, while the ref may also stop a fight for a cut or if he feels a fighter is too injured to continue. Fights that go the full 3 rounds of 5 minutes each are scored by a panel of judges on a "10-point must" system, just like in pro boxing.
Anyhow, I'm hoping I've piqued your interest and you'll give the UFC a chance while it's available on free TV instead of pay-per-view. There is a free UFC on Spike TV tonight at 9pm Eastern (6pm Pacific) - it's the live finale of the Ultimate Fighter reality show. They will air 3 fights for sure - a superfight between UFC legend Ken Shamrock and rising UFC star Rich Franklin, the middleweight finals: Diego Sanchez v. Kenny Florian, and the light heavyweight finals: Forrest Griffin v. Stephan Bonnar. The finalists are basically "minor league" MMA stars who are getting a chance to win a UFC contract and fight in the "big leagues."
All of the other participants in the show are fighting on the undercard, but they'll prob only show them if the fights on the main card end quickly, though we may get to see some highlights. If you missed the Ultimate Fighter show, they're having a marathon all day today on Spike, beginning at 9am Eastern. I think there's a fight at the end of every episode except for the first 2 episodes and episode 4.
If you tune in an hour early, at 8pm, you'll see the most recent episode, which features 2 fights - the light heavyweight semi-finals - neither of which go to judges decision (meaning they end by KO, TKO or submission). The Swick-Bonnar fight is particularly good.

As for how this is related to the Federalist Society, you'd be surprised to learn of the legal & regulatory battles regarding keeping MMA legal (Sen. John McCain was an early opponent of MMA), allowing it to be shown on cable TV, and eventually securing sanctioning by the country's most prominent athletic commissions (California recently agreed to sanction the sport beginning this summer.) The fact that it's being shown for free on cable TV is not only a huge victory for the sport, but an example of liberty triumphing over the forces of statism & regulation.
