Ratings: Two and a Half Men gets 28 million viewers, NBC tanks

CBS had a monster night as 'Two and a Half Men' scored a 10.3 rating and 28 million viewers. Dancing with the Stars premiered with a 3.9 and Hell's Kitchen ended with a 2.5.
The Sing-Off premiered to a 1.8 (how disappointing). I doubt that The Sing-Off will be breaking 2 for the rest of the season. Poor NBC. (Also, I'm a little annoyed now that The Sing-Off will have So You Think You Can Dance-like ratings for the rest of the season...)
Hawaii Five-0 premiered with a 3.4.
From TVbytheNumbers:
CBS easily won the first night of the season as Two and Half Men scored nearly 28 million viewers to go along with its 10.3 adults 18-49 rating (leading not only the night, but any scripted show in the 2010-11 season by a wide margin).Things were much gloomier for NBC. The Sing Off didn't crack a 2.0 rating and the premiere of The Playboy Club managed only a 1.6 adults 18-49 rating.
