Idol drew 23.5 million viewers over its two-hour broadcast and more than doubled its competition among adults 18-to-49, pushing Fox to another overall Tuesday win.
Parenthood, meanwhile, drew 8.1 million viewers, despite NBC's continuous promotion during the heavily watched Winter Olympics. The show retained most of its Biggest Loser lead-in (8.3 million viewers), which wasn't much of a boost, considering Loser was down 11 percent from its last episode before the Olympics.
The silver lining for NBC, however, is that Parenthood won the 10/9c timeslot in the demo, which was good enough to move the network to third place overall for the night.
CBS took the silver medal, but all its shows fell a bit after a two-week break. NCIS (19.7 million viewers) held up fairly well, but NCIS: Los Angeles (15 million viewers) was down 24 percent in the demo and The Good Wife (13.3 million viewers) lost 13 percent in the demo going against Parenthood.
ABC fell to fourth for the night, as Lost (9.2 million viewers) tumbled 13 percent to its lowest demo rating of the season. It was bookended by a Lost repeat (4.3 million viewers) and a 20/20 special (5.4 million viewers).
