Holy s-alsa, Dancing with the Stars is popular! 21.2 million viewers watched its season premiere last night.
In comparison, only 9.9 million people watched the 2-hour Heroes season premiere over on NBC (down 25% from last year; looks like people may still not have forgiven the show for last season).
CBS's numbers increased as the night progressed - with 14.9 million viewers for Two and a Half Men and 16.9 million for CSI: Miami.
Over on ABC, 9.4 million watched the premiere of the final season of Boston Legal.
