Conan Ratings Win: TBS Debut Beats Leno And Letterman

Conan O'Brien's return to television demolished his late night competition in the ratings.

The premiere of "Conan" on TBS drew 4.2 million viewers, with a whopping 3.3 million of them in the coveted 18-49 demographic.

By contrast, 3.5 million viewers tuned into Jay Leno's "Tonight Show," with 950,000 in the 18-49 demo, and David Letterman's "Late Show" drew 3.4 million viewers, with 1.4 million in the demo.

Of course, the ratings for O'Brien will likely drop in the coming weeks, but he and TBS can still cheer about the figures for his debut.
