Jimmy Kimmel RatingsIt was a very good week for Jimmy Kimmel. Last Thursday, Jimmy Kimmel Live! had its first in-season victory over The Tonight Show With Jay Leno. Even though he doesn’t come on until midnight, the ABC host beat his NBC rival by 4% in adults 18-49 on May 10. The fact that Kimmel’s Nightline lead-in had its highest rating for the week as well helped. Kimmel also beat out David Letterman at CBS in adults 18-34: Jimmy Kimmel Live! topped Late Show With David Letterman on May 7 (+5%), May 9 (+60%), and May 11 (+20%). The May 11 show, a Friday, was a Kimmel repeat vs. a new Letterman.

Kimmel also outperformed The Late Late Show With Craig Ferguson in 18-49 by 48% last week, and Late Night With Jimmy Fallon by 15% in 18-49 and 22% in total viewers. The ABC upfront host and this year’s White House Correspondents’ Dinner headliner saw his total viewership and demo draw grow 2% during the May 7 week, his best performance in six months. Jimmy Kimmel Live!’s growth, the only one among the late-night talk shows, could turn this season into his most watched since 2006-2007.
