It appears that a large portion of UFC live event programming will be getting shuffled a bit later in the year. Currently UFC events air on Fuel TV and FX, along with four a year on the main Fox network. According to Sports Media Watch (via SBJ) though, Fuel is about to be re-branded and FX will no longer be airing any sports at all:
News Corporation will convert the Fuel cable network into general sports channel ‘Fox Sports 2′ this August, Sports Business Journal reported Monday. The launch of Fox Sports 2 will coincide with the conversion of Speed Channel to Fox Sports 1.
Fox Sports 1 and Fox Sports 2 will be the chief outlets for News Corp. sports programming. FX, which aired college football coverage the past two seasons and previously televised baseball and NASCAR, will no longer carry sporting events. Fox Soccer is expected to be converted into a general entertainment channel.
While the UFC isn't specifically mentioned there, their live events obviously fall under the banner of "sports programming". You'd have to assume that FX events will move to Fox Sports 1, while Fuel events will clearly be on Fox Sports 2. It'll be interesting to see how this affects viewership, considering that Speed isn't currently in as many homes as FX (though the numbers are close - 86 million homes for Speed, about 98 million for FX).
In addition to that, we'll have to wait and see see what happens to The Ultimate Fighter. Is it going to be considered sports programming and flipped to a Fox Sports channel as well? Or will it stay on FX? I'm sure we'll be hearing from UFC president Dana White about all of this soon.
