Leno worked on late night television. He became host of "The Tonight Show" in 1992 when Johnny Carson retired. In 2007, during the writer's strike, Leno sided with the writers, even though he returned to his show after two months (without the writers besides himself) so that his staff would not be out of work. Despite leading the late-night ratings, he was forced out as host of the Tonight Show in 2009 to make way for Conan O'Brien. On March 1, 2010, became "The Tonight Show" host once again, because of poor ratings with both himself and Conan O'Brien. Leno hosted his last episode of the Tonight Show on February 6, 2014.
