Late Night Race Heats Up as O’Brien AND Letterman Increase Their Leads—O’Brien with 18-49 Year Olds, Dave With Total Viewers

Jul 23, 2009  •  Post A Comment

NBC’s “The Tonight Show With Conan O’Brien” widened its lead over CBS’ “Late Show With David Letterman” last week among adults 18-49 year olds.

At the same time “Late Night With David Letterman,” buoyed by a much-publicized appearance by Paul McCartney, had its biggest victory in nine years over "Tonight" among total viewers.

For the week of July 13-17, “Conan” averaged 1.38 million adults 18-49 (1.0 rating/ 5 share), compared with “Letterman’s” 1 million (0.8 rating/3 share). “Conan’s” 37% margin of victory over “Letterman” was up over the show’s 29% win the week before.

However, “Letterman” 3.5 million total viewers was significantly more than “Conan’s” 2.7 million viewers.

  1. You guys should ignore the NBC press release headline and do the math. Conan’s lead in the 18-49’s did not grow, it actually slightly shrunk. Just look at the numbers week to week and do the math. Letterman’s overall lead is growing, Conan’s demo lead is shrinking – I guess NBC feels they need to resort to out and out deception.

  2. Letterman hosts the Late Show, not Late Night. It’s a 5-sentence story, you can’t check what you write before posting it?
