I don' watch UFC anymore, but the first event I saw, somewhere in the single digits I believe, stuck with me. I saw one fighter execute a takedown skillfully, then scissored his opponent around his midsection with his legs, trying to get an ankle lock. His arms were too short to effectively do this, though, and his opponent was throwing some glancing blows into his kidneys. The mounting fighter kind of mentally shrugged (You could see him make up his mind just from his facial expressions) and then proceeded to start punching his opponent in the groin as hard as he could again and again. All told, I think he hit him some twenty-three times below the belt. He won, and that's when I understood that this kind of fighting was ushering a new era of brutality. If they changed to rules to disallow this, I'm glad, but I haven't watched in a while.
There are lots of rules now:
No hitting behind the head, no eye gouging, no groin hits, no kicking when hands on the ground, etc. Its nothing like the first set of UFC matches. There is also a recovery period, point deduction or even disqualification if you do any of those things.
The UFC of the early days was not able to get recognition because of their lack of rules but now with the 'safety' rules enforced more states and countries are allowing it.
There are talks that the UFC is going to be sold for $4 billion dollars but White will remain as president, at least for now. That's a massive amount of money and we can expect to see the UFC brand be commercialized more than ever before!
