We now return to our regularly scheduled programming...
Other than a short-lived period fueled by good guests and an on-air admission of an extortion attempt and sexual relations with staff members, Conan and the "Tonight Show" winning the demos had been the trend of the late night wars pretty much since taking over for Jay. Though I'm sure some will twist this into "Letterman's ratings drop due to scandal!"
On Friday Conan pulled a 1.1/5 (rating/share) with adults 18-49 in local Nielsen People Meter markets. Letterman and "Late Show" pulled a .9/4 on Friday night. Conan, as is always the case won with adults 18-34 too, and by a landslide with a 1.0 rating vs. a .5 rating for "Late Show".
But you don't need to worry about CBS canceling "Late Show" or getting rid of Letterman!
