TBS has extended late-night TV show host Conan O'Brien's contract through November 2015, the network announced Monday.

Conan, which airs Monday through Thursday at 11 ET/PT on TBS, premiered in November 2010 and has done well with young adults "scoring a younger median age than any other late-night talk show," according to TBS. (By extending him into 2015, the network exercised an option to fulfill the remainder of the five-year contract he signed in 2010.)

"When we invited Conan O'Brien to come to TBS, we knew he would bring with him a passionately loyal following of young adults," said Michael Wright, head of programming for the network.

"Conan and his colleagues at Team Coco have gone far beyond that by making Conan the top late-night brand in the digital arena. We are proud to extend our relationship with Conan as he continues to forge the future of late night. I just wish we didn't decide to tell him on April Fools' Day."

Starting Monday night, Conan hosts a week of shows in Atlanta celebrating the 2013 NCAA Men's Final Four.

Conan's ratings year-to-date average 906,000viewers, though the audience is particularly strong among ages 18-34. And, according to TBS, he's particularly hot on social media, and the Team Coco app won the 2012 Emmy for Interactive Media.
