Conan's Ratings

Last night, Conan O'Brien's new show debuted on TBS. It drew 4.2 million viewers, beating both Jay Leno and David Letterman. Um, but not by much and, worse, that's no spectacular debut even for cable. Where are all the fans who promised to follow him and support him? His ratings might go up, but by most accounts that will probably drop and he'll eventually be even with Leno and Letterman. So, what did this get him other than a martyr card? A good deal of the reviews I've seen are all about the ratings because when it is about the content it's mediocre at best, especially the interviewing. So he's just going to do another damn talk show? Like the one he failed with at NBC? Like all of the ones that are failing on all the networks right now?
