TV Ratings: 'Idol,' 'The Office,' 'Big Bang' and 'Two and a Half Men' Hit Lows

NBC

"The Office"

Thursday night was not terribly kind to any of the broadcast networks, with Fast National ratings down across the board. Cable returns won't come until later on Friday, but it's safe to expect a healthy chunk of viewers tuned into ESPN and the NFL Network's live coverage of the 2013 draft.

Back from encores, CBS did top the night in adults 18-49 (2.6 rating) and total viewers (11. 9 million). The Big Bang Theory (4.2 adults), while it may have topped the night, was down a full point in the key demo to a season low. Two and a Half Men (2.8 adults) took a steeper drop of 1.1 points to a series low. Person of Interest (2.4 adults) was only down three tenths of a point from its last original, while Elementary (2.0 adults) was off just a tenth.

American Idol (2.7 adults) was down three tenths of a point for an all-time low in regularly scheduled telecast. Glee (1.8 adults) dropped three tenths of a point, giving Fox an average 2.2 rating with adults 18-49 and 8.2 million viewers.

Another season low came for Wife Swap (1.1 adults), down four tenths of a point on ABC. Grey's Anatomy (2.7 adults) was down two tenths of a point, leading into the night's only grower: Scandal (2.8 adults). If the series' two tenths growth holds in finals, and stays above Grey's, it will tie its series' high and be the first time the ABC drama has beaten its lead. ABC averaged a 2.2 rating with adults 18-49 and 6.4 million viewers.

On NBC, Community (1.0 adults) dipped three tenths of a point to tie a low. The Office (1.7 adults), heading into the final stretch, was down two tenths of a point for a series low. Parks and Recreation (1.3 adults), down four tenths of a point, was also at a low. At 10 p.m., Hannibal (1.0 adults) dropped a concerning four tenths from last week's episode -- marking the lowest score for the series to date. NBC averaged a 1.1 rating with adults 18-49 and 2.5 million viewers.

The CW tested the waters with the backdoor pilot for Vampire Diaries spinoff The Originals at 8 p.m. Pulling a 0.9 adults rating, it was down a tenth of a point from last week. Beauty and the Beast (0.5 adults) was also down by a tenth, giving the network a 0.7 rating with adults 18-49 and 1.7 million viewers.

Univision averaged a 1.4 rating in the key demo and 3.3 million viewers.
