Ratings: American Idol down 34% from last year

Update: American Idol adjusted up to 5.1 and 16.1 million viewers.

American Idol had a 5.0 adult rating last night, down 34% from a similar show last season. The show had 15.8 million viewers.

This was still not enough to beat The Voice this week which had a 5.4 adult rating. Can Idol pick up the pace tonight? The show just might be stabilizing.

NCIS had 18 million viewers, beating Idol easily at number of viewers. It had a 3.4 rating.

The rest of the numbers:

From FOX_Research:

#FOX was No. 1 last night in Adults 18-49 (5.0/13), Adults 18-34 (3.7/11), Total Viewers (15.8 million) and Teens (3.3/11) #AmericanIdol

@AmericanIdol was the top program of the night in Adults 18-49 (5.0/13), Adults 18-34 (3.7/11), and Teens (3.3/11)

#AmericanIdol beat the No. 2 program of the night, CBS’s NCIS, in A18-49 by +47% (5.0/13 vs. 3.4/9) and +106% in A18-34 (3.7/11 vs. 1.8/6)

From TVbytheNumbers:

A two hour American Idol led Fox to the ratings win on Tuesday, as Fox had the highest rated Tuesday night among adults 18-49 for any network this season. Idol's 5.0 adults 18-49 rating was a tenth below last Wednesday's Idol telecast (but continues well below last season's ratings), expect that typical finals adjustments will eliminate that gap.

NCIS dipped to a season low 3.4 adults 18-49 rating, down 6% vs. a 3.6 rating last week. Interestingly, NCIS: Los Angeles was up noticeably, its 3.1 adults 18-49 rating rose 15% vs. a 2.7 rating last week. Unforgettable fell 5% to a series low 1.9 adults 18-49 rating, vs. a 2.0 rating last week.

The Biggest Loser kept losing, its 2.0 adults 18-49 rating was a season low, down 13% vs. a 2.3 rating last week. The season finale of Parenthood got a boost, rising to a 1.9 adults 18-49 rating, up 12% vs. a 1.7 rating last week.
