'Tonight Show' vs. 'Daily Show' may be the latest battle in the late-night wars, as a surprise ratings report has NBC and Comedy Central clashing over who's on top. Is Jon Stewart, as the numbers suggest, now more popular than Jay Leno?

For the first time, Stewart's 'The Daily Show' has bested Leno's 'Tonight Show' in a key segment of viewers. However, NBC execs, ever stubborn when it comes to defending Leno, aren't taking the news lying down.

According to EW.com, while Leno's 'Tonight Show' viewership still tops the ratings in overall viewers, as it has for years, Comedy Central is celebrating the fact that during the most recent quarter, Stewart drew a few thousand more people than Leno in the crucial "Adults 18-49" demographic.
