Ultimate Fighting Championship is a fighting sport which is a combination of Jujutsu, boxing, wrestling and other martial arts.

Ultimate Fighting Championship events have become very popular in places like Japan, Brazil and the United States, where fights are often seen on television's Pay Per View system. In the United States, championship fights are usually held in Las Vegas, pretty much like in boxing.

Some of these sport's stars include Tito Ortiz, Ken Shamrock and Antonio Rodrigo Nogueira.
