The Ultimate Fighting Championship (UFC) is an American mixed martial arts (MMA) Dana White has been UFC president since 2001. Under White's stewardship, the UFC has grown into a globally popular multi-billion-dollar enterprise.
The purpose of the early Ultimate Fighting Championship competitions was to identify the most effective martial art in a contest with minimal rules and no weight classes between competitors of different fighting disciplines like Boxing, Kickboxing, Brazilian Jiu-Jitsu, Sambo, Wrestling, Muay Thai, Karate, Taekwondo, and Judo. In subsequent events, fighters began adopting effective techniques from more than one discipline, which indirectly helped create a separate style of fighting known as present-day mixed martial arts. In 2016, UFC's parent company, Zuffa, was sold to a group led by William Morris Endeavor (WME–IMG), including Silver Lake Partners, Kohlberg Kravis Roberts and MSD Capital for US$4.025 billion.
