Fox lost the broadcasting rights to the Bowl Championship Series to ESPN beginning in 2010. In response, Fox introduced a Saturday "game of the week" on FX in 2011, featuring games from the Pac-12, the Big 12 and Conference USA (the rights to which were later assumed by Fox and Fox Sports 1); Fox also signed deals to carry two new championship games created through conference realignments that occurred in 2010 and 2011: the Big Ten Conference Championship through 2016 (as part of Fox Sports' involvement with the Big Ten Network), and the Pac-12 Championship through 2017 on an alternating basis with ESPN. With the replacement of the BCS with the College Football Playoff, Fox lost the broadcasting rights to the 2015 Cotton Bowl Classic onwards again to ESPN.
