In February 2009, mixed martial arts promotion Strikeforce announced a three-year broadcast agreement with Showtime, allowing it to broadcast up to 16 events per year, as well as a deal with sister network CBS for an option to produce up to four events for that network; Strikeforce ended its run on Showtime when the league folded in January 2013. In addition to broadcasting big-ticket Strikeforce events on Showtime, the promotion also announced it would produce "ShoMMA: Strikeforce Challengers", an event series highlighting up-and-coming fighters.
