No Leno Bounce: Conan Dominates Ratings Monday

“Tonight” doubles demo score vs. “Late Show.” Dave retakes lead among all viewers

Conan O’Brien’s "Tonight Show" continued its ratings resurgence Monday, doubling "Late Show with David Letterman" in adults 18-49 and easily beating Jay Leno’s primetime performance.

"Tonight" averaged a 1.8 rating in Nielsen’s 25 metered markets with demo information, twice as high as Letterman’s 0.9 average and the 1.2 for "Nightline." That’s down a tick from Friday’s recent high of a 1.9 for Conan.

"Late Show" retook its advantage in the broader household average, scoring a 3.2 by that measure vs. a 3.0 for "Tonight."  Keep in mind these numbers, along with the demo scores, will shift a bit when final national ratings are released next week.

"Tonight," despite airing much later than "The Jay Leno," continues to outdraw Leno’s soon-to-be-dead show in the demo. Monday’s "Leno" at 10 averaged a 1.3 in the demo, falling by double digits vs. last week — and getting no bump at all from news reports of Leno speaking out about LateNightCrisis2010.
