A minimum of 13 games will come from the newly expanded conference (Colorado and Utah are being added to the lineup.) The cable channel will also have games from the Big 12 and Conference USA. Games will air Saturdays, both during the day and in prime time. From Variety:
Fox has used FX as a sports platform in the past, but not since 2006. When Fox sports topper David Hill makes his Olympic bid in the next few months for the 2016 Summer Games in Rio de Janeiro and beyond, part of his pitch will be that events would be telecast live on FX.
FX runs a lot of repeats on the weekend, so this will be a way to boost ratings - and subscriber fees. From the LAT:
If you want big subscriber fees, you need big sports. That is one of the motivations behind News Corp.'s decision to put college football on its cable network FX. Although FX has had creative and commercial success with its dramas and comedies such as "Rescue Me," "Sons of Anarchy" and "It's Always Sunny in Philadelphia," it trails rival networks including TNT and TBS in license fees. TNT's and TBS' big-ticket sports programming includes the NBA, baseball and college basketball.
