Ultimate Fighting Championship
The UFC is a U.S.-based MMA organization, recognized as the largest MMA promotion in the world. The UFC is headquartered in Las Vegas, Nevada and is owned and operated by Zuffa, LLC.
The UFC was started as a tournament to find the world's best fighters irrespective of their style, and was based upon Brazilian vale tudo fighting or No Holds Barred. Early UFC fights were less sport than spectacle, which led to accusations of brutality and "human cock fighting" by opponents.
As political pressure mounted, the UFC reformed itself, slowly embracing stricter rules, becoming sanctioned by state athletic commissions, and marketing itself as a legitimate sporting event.
