Beginning his stand-up career while in college, Leno moved to Los Angeles and wrote for television. He became guest host of The Tonight Show in 1987 and—when Johnny Carson retired in 1992—NBC chose Leno as his replacement. In 2009, after 17 years as host and an Emmy, Leno handed the show to Conan O’Brien. But, only a few months later, NBC caused controversy by bringing Leno back as host and bumping O’Brien. Leno left The Tonight Show when his contracted ended in 2014.
