With usage among adults 18-49 down week to week and no series posting any growth across the broadcast networks, Thursday night proved a particular downer for Fox's American Idol.

Following Wednesday's performance show low, Idol (2.7 adults rating) was down two-tenths of a point from the previous Thursday for the lowest demo score in the show's 11-year history. The hour obviously is subject to adjustment when final ratings are available. Idol led into a one-hour season finale of Raising Hope (1.3 adults), which was down by a tenth of a point from its most recent Tuesday outing. Fox averaged a 2.0 rating with 18-49-ers and 7.5 million viewers.

ABC's Wife Swap (1.4 adults) was down three-tenths of a point from last week's premiere, leading into Grey's Anatomy (2.8 adults), which dropped two-tenths from last week. Scandal (2.6 adults) was only off by a tenth of a point, giving the network an average 2.3 rating with adults 18-49 and 7.1 million viewers.

Early returns for CBS coverage of the NCAA Men's Basketball Tournament regional semifinals, which are likely to see adjustment when final numbers are available, brought in a 2.3 rating with adults 18-49 and 6.9 million viewers.

With two episodes of 1600 Penn (0.7) -- both tying a series low -- as the only originals on NBC, the network averaged just a 0.8 rating with adults 18-49 and 2.6 million viewers.

The CW bested NBC in the demo for the night, with The Vampire Diaries (1.2 adults, off a tenth) and an even Beauty and the Beast (0.6 adults). The CW averaged a 0.9 rating with adults 18-49 and 2 million viewers.

Univision averaged a 1.4 rating with adults 18-49 and 3.5 million viewers.
