FX Networks is aiming to compete with large broadcast networks for ad buys by splitting their audiences and offering competitive CPMs. The newest network, FXX, aimed at the valuable 18-34 demographic, will launch September 2 and become the new home for such favorites as “The League” and “It’s Always Sunny in Philadelphia.” This announcement follows the launch of FXM, which airs movies, and will soon be home to original miniseries much like competitor HBO. The company also intends to launch FXNow this fall, offering on-demand streaming aimed to reduce DVR usage. The service will include FX original series as well as a rotating set of movies. Now that FX has clearly set its sights on such varied competitors as ABC, NBC, HBO, and Netflix, will other networks follow suit and diversify?
