'American Idol' wins night, but declines


Reality titans "American Idol" and "Dancing With the Stars" had a rough night Tuesday, while the series finale of "Jericho" concluded on a flat note.

Fox's 90-minute episode of "Idol" (24.4 million viewers and a 9.6 rating/24 share in the key adults 18-49 demographic) led the night but hit a season-low delivery. A special 9:30 p.m. airing of " 'Til Death" (10.8 million, 4.6/11) was its highest rating since the last time the sitcom had an "Idol" lead-in a year ago. Overall, Fox won the night in viewers and the demo (21 million, 8.3/21).

ABC was second with a "Dancing" results show at 9 p.m. (17.2 million, 3.8/9) that marked the series' lowest return since 2006, excluding specials. A "Dancing" recap served as a lead-in, and "Primetime: What Would You Do" (10.4 million, 3.2/9) won the 10 p.m. hour.

NBC was third with an on-par "Biggest Loser: Couples" (7.8 million, 3.1/8), followed by a repeat.

In fourth, CBS had a procedural repeat, "Big Brother" (6.0 million, 2.3/5) and the last episode of "Jericho" (6 million, 1.9/5). (Watch a clip from the "Jericho" finale.)

The CW's "Beauty and the Geek" (1.6 million, 0.7/2) was down a notch.
