Guess they have the Tea Party to thank for this one. Comedy Central’s The Daily Show made ratings history this past month, becoming the first late-night talk show in the past decade to rank No. 1 in the adult demo for an entire month other than Jay Leno’s The Tonight Show or The Late Show with David Letterman. Jon Stewart’s series averaged 1.3 million viewers among adults 18-49 for the month of October, followed by The Tonight Show with Jay Leno and The Late Show with David Letterman, which both averaged 1.2 million viewers. The Daily Show also had a 1.0 adult demo rating for the month, compared with 0.9 for Leno and Letterman.
