Leno has been under the gun ever since taking over for Johnny Carson back in 1992. With all due credit to Leno, those were some amazingly large shoes to fill in the first place.  For many, Leno's version of The Tonight Show was a pale comparison to what Carson made the show.

The battle for late night TV can be brutal and Jimmy Kimmel says that Leno just doesn't have the goods anymore.

Jimmy Kimmel says he has “disdain” for Jay Leno, saying his fellow late-night talk show host used to be funny but has “totally sold out.” Kimmel, whose “Jimmy Kimmel Live!” is moving from its 12:05 a.m. time slot on ABC to 11:35 – when it will be in head-to-head competition with Leno’s “The Tonight Show” on NBC, David Letterman’s “Late Show” on CBS, and Conan O’Brien’s show on TBS – told Rolling Stone Leno “hasn’t been a good stand-up [comedian] in 20 years.” “As a comedian, you can’t not have disdain for what he’s done,” he said. “He totally sold out. He was a master chef who opened a Burger King.”
