‘Parenthood’ wins the hour, but it’s not a great start

Without the Olympics in its way anymore, “American Idol” crushed the competition Tuesday night and gave Fox an easy win. NBC took the 10 p.m. hour with the launch of “Parenthood,” but considering the extensive promotion behind the small-screen adaptation of the Ron Howard film, Peacock execs aren’t exactly doing cartwheels as the series earned only a 3.1 rating/8 share in the 18-49 demo and was clobbered in total viewers by “The Good Wife.”  Parenthood 

“Parenthood,” however, did a nice job of retaining 94% of viewers from the final half-hour of its “Biggest Loser” lead-in. NBC’s two-hour reality skein earned a 3.1/8, 8.2 million, down 11% from its last pre-Olympics episode. “Parenthood,” starring Peter Krause, stayed consistent throughout the hour, and opened on par with what “Southland” (3.1/9) and “My Own Worst Enemy” (3.0/8) did last season.

After battling with the Vancouver Olympics for two weeks, “Idol” (8.6/22, 23.4m) secured the win for Fox as the 10 remaining male contestants competed in front of the judges panel.

Following “Idol,” CBS’s “NCIS” (4.1/11) was both the second-highest rated and second-most watched as 19.6 million tuned in. Spinoff “NCIS: Los Angeles” followed with a 3.1/8, 14.9 million, a strong showing against ABC’s “Lost,” which hit season lows. Alphabet’s island drama drew a 4.0/10, with 9.1 million watching in one of the most competitive hours of the week.

“The Good Wife” (2.7/8, 13.2m) was down 13% from its last original telecast, as “Parenthood” certainly cut into its audience, but the Juliana Margulies starrer still outdrew “Parenthood” by 5.2 million total viewers. Also at 10, ABC’s “20/20” special, “Before They Were Famous,” earned a 1.8/5, 5.4m.

Preliminary 18-49 averages for the night: Fox, 8.6/22; CBS, 3.3/9; NBC, 3.1/8; ABC, 2.5/7; Univision, 1.4/4; CW, 0.3/1.

In total viewers: Fox, 23.4 million; CBS, 15.9 million; NBC, 8.1 million; ABC, 6.3 million; Univision, 3.5 million; CW, 693,000.
