Season 10

The tenth season of It's Always Sunny in Philadelphia aired between January 14, 2015 and March 18, 2015 on FXX. It consists of 10 episodes.

Background
On March 28, 2013, FX announced that the show had been picked up for a tenth season. FX President John Landgraf stated that there may be more seasons after that: “Whether it goes beyond that depends on whether the people who created the show want to go and whether the audience still wants to watch."

On April 4, 2014 it was announced that FXX had signed RCG Productions to a 3-year contract to produce more comedy shows, including Season 11 and Season 12 of Sunny.

The renewal for It's Always Sunny -- picked up for two seasons of 10 episodes each -- which took the series through its 12th season. The series became the longest-running live-action comedy in cable history, and its 12 seasons will tie My Three Sons and Two and a Half Men for the second-longest-running American live action comedy in TV history.
