The Top Five American Idol performance show last night drew the reality giant’s smallest audience since the the first season, which aired in the summer of 2002. In total viewers (17.1 million) as well as adults 18-34, this was the lowest-rated Idol since Aug. 27 2002. In viewers, the Fox series was beaten by ABC’s Dancing with the Stars performance show Monday, which drew 19.6 million viewers. (Idol prevailed in the adults 18-49 demo, 6.0/18 vs. 4.1/12. In that demo, Idol was down 13% from last week). Fox’s Glee retained its best ever 82% of the Idol lead-in. The freshman dramedy (4.9/13 in 18-49) was down 6% in the 18-49 demo from last week.
Heading to its finale, ABC’s Lost (3.9/10) was up 5% in the demo from its last original. Having a Lost original vs. a repeat helped V at 10 PM. The ABC bubble freshman (2.2/6) was up 16% from last week. It was a seesaw at CBS, with NCIS (3.1/9) hitting a season low, down 11% from last week, and NCIS: LA (2.8/7) hitting a series low, while The Good Wife (2.4/7) went up 9% week-to-week. The rookie legal drama still lost in the demo to its new NBC competition at 10 PM, NBC’s Parenthood (2.6/7), which was also up 8% from last week, helped by a 14% spike for lead-in Biggest Loser (3.2/9). Fox won the night in adults 18-49 (5.5/15) and total viewers (14.5 million).
