Ratings: ‘America’s Got Talent’ Final 4 Leads NBC to a Win

The season two premiere of “Parenthood” also delivered solid numbers

NBC won Tuesday night thanks to the "America's Got Talent" final four and the season two premiere of "Parenthood."

Overall, NBC averaged a 2.8 rating/8 share in the key adults 18-49 demographic. ABC landed in the number two spot with a 2.3/7.

"America's Got Talent" was the top show of the night with a 3.8/11 from 9-10 p.m. The episode, which featured performances from the top four finalists — kiddie opera phenom Jackie Evancho, drag singer Prince Poppycock, crooner Michael Grimm and the performance troupe Fighting Gravity, scored the show's highest 18-49 rating since Aug. 2007.

"Parenthood" posted a 2.7/8 from 10-11 p.m., down 13 percent from last season's premiere, which aired following a major promo push during the 2010 Winter Olympics. Though "Parenthood" didn't match its series debut, Tuesday night's episode won its time slot and ranked as the show's third highest-rated telecast in the key demo.
