Mixed martial arts is a full-contact sport, that combines different fighting styles, including karate, boxing, kickboxing, wrestling, Vale Tudo, Muay Thai and Brazilian Ju jitsu.
MMA started out as a competition, as to find the best and most effective Martial Arts for real life situations of unarmed combat. Fighters where put up against each other with few rules. Later on, the fighters learned different fighting styles, that they combined with their own, at the same time promoters had to update the rules to increase safety for competitors, and to promote mainstream acceptance of the sport. After these changes, the sport has seen an increase in popularity with a pay-per-view business that competes with that of boxing and professional wrestling.
