FX (standing for Fox extended, suggesting “effects”) is the name of a number of related pay television channels owned by News Corporation’s Fox Entertainment Group. The FX logo is very similar to the logo of FOX only that it is black and doesn’t contain an O.
The channel’s most popular original shows are The Shield, Nip/Tuck, Damages, Rescue Me, Sons of Anarchy, Justified and American Horror Story, as well as the comedies It’s Always Sunny in Philadelphia, Louie, The League, Wilfred and Archer. Aside from new episodes of its ongoing series, the channel mainly airs re-runs originally broadcast on Fox in the 1990s and 2000s.
In 2010, Sons of Anarchy attracted an average of 4.9 million viewers per week, making it FX’s highest rated series ever, surpassing other hits The Shield, Nip/Tuck, Rescue Me and Damages.
