Jay Leno's ratings fall below Conan's on 'The Tonight Show'

For the first time, Jay Leno's average weekly ratings among 18-49-year-old viewers has fallen below Conan O'Brien's... (TV analyst Joe) Adalian noted that Leno averaged only a 1.0 rating and a 5 share last week versus O'Brien's 1.1/5 average -- despite the fact that CBS was airing repeats of Late Show with David Letterman, which drew a 0.8/3 in the demo. Moreover, Leno now benefits from a much stronger nightly lead-in -- with shows like Parenthood and The Marriage Ref being aired by the network in the 10 00 p.m. time period -- than O'Brien did when his lead-in was Leno.
Seven weeks in, Leno is averaging a 1.0 in the 18-49 demo while David Letterman averages a 0.8. These are precisely the same numbers "The Tonight Show" and "The Late Show" were pulling seven weeks into Conan’s “Tonight” tenure.

The chart also reminds us that before “The Jay Leno Show” started last September (at week 16 into Conan’s run, I think), Conan won the 18-49 race against Letterman every single week last summer.

Only after “The Jay Leno Show’s” arrival as Conan’s 10 p.m. lead-in did Conan begin losing to Letterman in 18-49 for the first time.
Coco will also make his first post-Tonight Show TV appearance on 60 Minutes this upcoming Sunday.
