The Ultimate Fighting Championship (UFC) is a mixed martial arts (MMA) promotion, founded in 1993 by Art Davie and Rorion Gracie. The organization was purchased from its parent company SEG in 2001 by Zuffa LLC, a promotional company owned by Las Vegas casino magnates, Lorenzo and Frank Fertitta and managed by Dana White (current president of operations). Since its inception, and through its current Zuffa management, the UFC has remained one of the more dominant MMA promotions in the world, playing host to a wide field of MMA fighters.
