Comcast is continuing to mull what to do with all of its NBCUniversal assets. The latest example: The Wall Street Journal reports today that NBCU is in talks with mixed-martial arts league Ultimate Fighting Championship to take a controlling stake in the company’s struggling G4 cable network. The league is looking for an outlet to promote its sport to a growing fan base of young men, the exact target demographic of G4, which focuses on gaming and gadgets but is struggling ratings-wise and recently was dropped by DirecTV. It makes sense — UFC has a distribution deal with Spike TV that expires at year’s end and already shows events on Comcast’s Versus network — but NBCU should watch out for that backlash: It has added wrestling programming to its Syfy channel, sparking complaints from fans angry that their core sci-fi programming is being pushed aside.
