Additionally, FX has renewed comedy “Louie” for a third season of 13 episodes, and picked up new comedy “Wilfred” for a second episode of 13 seasons, network chief John Landgraf announced at Summer TV Press Tour 2011.

Landgraf himself has just been signed to remain president of FX for three more years.

TV critics still have not gotten over Landgraf canceling cop dramedy “Terriers” and they wanted him to talk about what had happened, all these months later.

Landgraf, who’d wisely held a phone conference-call wake when he pulled the plug on their darling back in December, noted the number of original scripted series on cable has increased by 35 percent year to year. There are so many original scripted shows on television, the public’s “awareness” and “intent to view” levels on commercial broadcast shows frequently does not break above 50 percent. And, on cable shows, it can be as low as 30, 20 or even 10 percent, Landgraf explained.

“When the consumer can’t even differentiate how much product there is, there’s probably too much,” he added.

“‘Men of a Certain Age’ is arguably the most critically acclaimed show Turner has ever had on the air, and yet at a certain point there’s just so much competition…if ratings really aren’t there, it just gets tougher and tougher to say ‘Well we don’t’ care. We declare it’s a success’,” Landgraf continued.

“ If I hadn’t canceled ‘Lights Out’ and ‘Terriers,’ then [Ryan Murphy’s new FX series] ‘American Horror Story’ wouldn’t exist. I can’t make an infinite number of shows.”
