Mixed martial arts (MMA) is a full-contact combat sport that allows the use of both striking and grappling techniques, both standing and on the ground, from a variety of other combat sports and martial arts. Various mixed-style contests took place throughout Europe, Japan and the Pacific Rim during the early 1900s. In 1980 CV Productions, Inc. created the first regulated MMA league in the United States named Tough Guy Contest, later renamed Battle of the Superfighters, sanctioning ten tournaments in Pennsylvania. However, in 1983 the Pennsylvania State Senate passed a bill prohibiting the sport. The combat sport of vale tudo that had developed in Brazil from the 1920s was brought to the United States by the Gracie family in 1993 with the founding of the Ultimate Fighting Championship (UFC).
