Jay Leno, <I>The Tonight Show with Jay Leno</I>
Seen here as a senior at Andover High School in Andover, Massachusetts, Leno got his late-night start guest-hosting for Johnny Carson. He took the helm of The Tonight Show in 1992 and remained there until 2009, when Conan O'Brien took over. Less than a year later, Leno returned as host after the awkward late-night war between him, NBC, and Conan O'Brien. Leno took his final bow on The Tonight Show in 2014.
