Ratings Chart Attack!

Part two of the season premiere of “24” on Fox held steady from its Sunday night start, but record performances from two of its comedies helped CBS place first for the night among the broadcast networks.

“24” scored a 4.1 rating/10 share among adults 18-49 and drew 12.3 million viewers, according to preliminary Nielsen Media Research numbers. The episode was down just a tick from Sunday’s part one, but its ratings were good enough to give Fox second place for the night.

New episodes on CBS gave the network a first-place finish in the demographic (4.3/11) and in total viewers (13.8 million). New episodes of “The Big Bang Theory” (4.4/11, 11.8 million) and “How I Met Your Mother” (4.8/12, 11.8 million) posted series highs in the demographic, while “Two and a Half Men” (5.6/13, 17.1 million) posted a season high; all three programs won their half-hour timeslots. “Worst Week” (3.3/8, 10.5 million) and “CSI: Miami” (4.1/10, 15.7 million) were average for the season.

Reality programming on ABC gave the network a third-place finish (3.1/8, 8.2 million). “The Bacherlor” (3.2/8, 9.1 million) was in line with its season opener last week, while a new episode of “True Beauty” (2.8/7, 6.5 million) slid 13% from last week.

On NBC, a new episode of “Superstars of Dance” (1.9/4, 7.1 million) performed to its lowest rating to date, down 30% from last week, while a new episode of “Momma’s Boys” (1/7/4, 4.6 million) remained on par. NBC took fourth for the night with a 1.8/4 (6.2 million).

The CW placed fifth (1.4/3, 3 million) with new episodes of “Gossip Girl” (1.3/3, 2.9 million), flat from last week, and “One Tree Hill” (1.5/3, 3.1 million), up 25% in the demographic. Among women 18-34, the network averaged a 2.9 rating.
