FX has given an unprecedented four season pick up to comedy “It’s Always Sunny in Philadelphia,” taking it through 18 seasons. With season 15 due next year, “It’s Always Sunny in Philadelphia” will set the record as the longest-running live-action comedy series in television history, bypassing class comedy “The Adventures of Ozzie & Harriet,” which aired for 14 seasons (from 1952 to 1966).
Debuting in August 2005, the series follows “The Gang”, a group of five misfit friends: twins Dennis (Glenn Howerton) and Deandra “Sweet Dee” Reynolds (Kaitlyn Olson), their friends Charlie Kelly (Charlie Day) and Ronald “Mac” McDonald (Rob McElhenney), and (from season 2 onward) Frank Reynolds (Danny DeVito), Dennis and Dee’s father. The Gang runs the fictional Paddy’s Pub, an unsuccessful Irish bar in South Philadelphia.
Through the end of season 14, a total of 154 episodes of “It’s Always Sunny in Philadelphia” have been produced.
