James Douglas Muir "Jay" Leno is an Emmy Award-winning American stand-up comedian and television host who succeeded Johnny Carson as host of "The Tonight Show" on May 25, 1992. He hosted the show until May 29, 2009 when, despite his high ratings, he was replaced by Conan O'Brien. The poor ratings which Conan O'Brien received as host of "The Tonight Show" resulted in NBC bringing Leno back as host on March 1, 2010. He continued to host the show to critical and popular acclaim. In 2013, despite still having the highest late night television ratings, NBC decided to replace Leno with Jimmy Fallon as host. Leno's final show aired on February 6, 2014.
