Answer by taking a quote from the following article:

The Jay Leno Show is an American talk show created by and starring Jay Leno. Premiering on NBC on September 14, 2009, the program aired on weeknights at 10:00 p.m. ET/PT through February 9, 2010. The program was modeled upon the format of a late night talk show--specifically, Jay Leno's incarnation of The Tonight Show, opening with a comedic monologue, followed by interviews with celebrity guests and other comedy segments. Sketches from The Tonight Show (including Headlines and Jaywalking) were carried over to The Jay Leno Show, along with new sketches.

In early January 2010, multiple media outlets reported that, following the 2010 Winter Olympics, The Jay Leno Show would be shortened to 30 minutes and begin airing weeknights at 11:35 pm ET, with Conan O'Brien and Jimmy Fallon's shows following it beginning at 12:05 am on March 1, 2010. On January 10, NBC Universal Television Entertainment Chairman Jeff Gaspin confirmed that The Jay Leno Show would indeed move to 11:35.  Leno immediately accepted the return to 11:35 p.m., calling the move "all business." He had made it known in the press in November 2009 that he wished to return to his old timeslot; behind the scenes, Leno had privately indicated that he did not believe the 10:00 experiment would work. On the other hand, O'Brien's contract stipulated that the network could move the show back to 12:05 a.m. without penalty, a loophole put in primarily to accommodate sports preemptions, the network's traditional nightly Wimbledon tournament highlights show, and specials such as New Year's Eve with Carson Daly.  O'Brien did not seriously respond for several days after the announcement, then drafted a press release explaining why he felt it was unfair to him, his staff, Fallon, and the legacy of The Tonight Show to move the show past midnight. He concluded by saying that he "cannot participate in what I honestly believe is [The Tonight Show's] destruction." O'Brien received an outpouring of celebrity and viewer support for rejecting the move, while Leno received heavy criticism. On January 21, O'Brien signed a $45 million deal allowing him to leave the network, and aired his final episode of Tonight on January 22; Leno returned as host of Tonight on March 1.
