The only US television network dedicated to soccer is to close. Fox announced on Thursday that Fox Soccer will make way for a new youth entertainment network in September.

The future of Fox Soccer had been in doubt since it lost the rights to English Premier League matches to NBC last October. Fox said that it would be replaced by FXX, a new network to complement FX, in September. The rest of Fox Soccer's matches, including Uefa Champions League fixtures, will be transferred to Fox Sports 1, a new general sports network that is expected to launch in August.

Fox said that the line-up for FXX would consist of original series, movies and acquired series targeting adults 18 to 34, a slightly younger demographic than the 18-to-49 audience attracted by FX. It said that FXX would initially be available in 74 million TV homes in the US.

The new channel joins FX and the movie-oriented FXM; all three networks would share the same sensibility, FX Networks president John Landgraf said in the announcement Thursday. "All told, the three networks will air 25 original series in the next few years," he said.

The new channel will be anchored by the comedies It's Always Sunny in Philadelphia and The League, two veteran series that until now have originated on FX. In addition, Legit will move to FXX, as well as the FX late-night series Totally Biased with W Kamau Bell, which will expand to a five-nights-per-week schedule.

Coming to FX this July is a new drama series titled The Bridge. Starring Demian Bichir and Diane Kruger, it centers on two detectives hunting down a killer operating on both sides of the US-Mexican border. The show is based on the Scandinavian series Bron.

A pilot for another future series, Tyrant, will be directed this summer by two-time Oscar winner Ang Lee.

FX's first limited series will be Fargo, inspired by the acclaimed 1996 film of the same name. This 10-episode drama, which will tell an all-new story, will be executive-produced by the film's creators, Joel and Ethan Coen.
