It’s Always Sunny In Philadelphia scored about 757,000 viewers in its season debut on FXX last night at 10 PM – fumbling nearly 300,000 viewers compared to its previous season debut on FX network. But, the show logged 30,000 more 18- to 34-year-old guys than it had with its last season debut on FX, so FXX’s is calling it a win, since that’s the new network’s target audience (it shed 125,000 women 18-34). FX comedies Sunny and The League last night made the move to FXX in order to populate the new comedy network spinoff. In making the move,  The League, at 10:30 PM, gave up about 121,000 viewers, debut to debut — about 22,000 of them men 18-34. FXX is currently available in 26 million fewer homes than is FX. After that, the nightly debut of Totally Biased With W. Kamau Bell at 11 PM clocked an average of 183,000 viewers — 90,000 of them in the 18-34 age bracket, which is a 59% retention of that demo compared to the show’s last weekly cycle.

FXX this afternoon noted Sunny and The League outstripped ABC, CBS and NBC from 10-11 PM in adults 18-34 and men 18-34. “To have just launched the channel three days ago and get these ratings is thrilling”, FX Networks and FX Productions CEO John Landgraf said this afternoon. “The delivery of these shows needs no qualification, they are proven appointment viewing for young adult audiences.”
