Strikeforce is a world-class mixed martial arts cage fight promotion which, on Friday, March 10, 2006, made history with its “Shamrock vs. Gracie” event, the first sanctioned mixed martial arts fight card in California state history. The star-studded extravaganza, which pitted legendary champion Frank Shamrock against Brazilian Jiu-Jitsu black belt Cesar Gracie at San Jose’s HP Pavilion, played host to a sold-out, record crowd of 18,265. Since 1995, Strikeforce has been the exclusive provider of martial arts programming for ESPN and, after 12 years of success as a leading, world championship kickboxing promotion, the company unveiled its mixed martial arts series with “Shamrock vs. Gracie.” Since then, it has co-produced the first SHOWTIME PPV mixed martial arts event in history with its world championship “Shamrock vs. Baroni” card on June 22, 2007.
