Strikeforce was a U.S.-based mixed martial arts and kickboxing organization based in San Jose, California which ran from 1985 to 2013. It was headed by CEO Scott Coker. Its live events and competitions have been shown on CBS and Showtime in the United States, Super Channel in Canada, Primetime in the United Kingdom, SKY PerfecTV! in Japan, HBO Plus in Brazil, Space TV in Latin America and the Caribbean, and on the American Forces Network.
Strikeforce was purchased by UFC owners Zuffa LLC, who eventually closed the promotion and brought the remaining fighter contracts into the UFC roster.
