TV ratings: ‘American Idol’ leads the night as ABC, NBC grow

With a fresh round of auditions in Detroit, “American Idol” was again the top-rated show on the major networks Wednesday night and gave Fox a comfortable win, though as expected it fell from last week’s premiere.

The Motor City visit, kicking off the second week of the show’s 13th season, drew 13.2-million viewers on average, down 12% in total viewers from the season opener, according to preliminary figures from Nielsen. Among the advertiser-desired 18-to-49 age group, “Idol” earned a rating of 4.0, down 13% week to week; however, the number is a slight improvement on last Thursday night’s episode.

Boasting Keith Urban, Jennifer Lopez and Harry Connick Jr. in the judges chairs, the veteran reality show is hoping to regain some viewers after taking a ratings slide last year.

The next highest-rated show was ABC’s “Modern Family,” up 9% from last week to a 3.5 in the key demographic. It drew 9.74-million viewers overall.

The entire ABC lineup improved week to week, with “The Middle” leading off up 22% among young adults and “Suburgatory” rising 13% from last week’s premiere. The freshman Rebel Wilson comedy “Super Fun Night” and “Nashville” also posted gains.

NBC dramas also improved. “Revolution” increased its 18-to-49 rating by 15% from last week to a 1.5, followed by “Law & Order: SVU,” up 29% from last week to a 1.8. The new Dick Wolf-produced 10 p.m. drama “Chicago P.D.,” a spinoff from “Chicago Fire,” grew 7% week to week for a demo rating of 1.6, tied with time-slot competition on CBS — a slipping episode of “CSI.”

“CSI” lost 20% of its 18-to-49 rating from last week, after “Criminal Minds” posted a 2.2 rating, down slightly from a Wednesday ago.
