The network opened the night with the Peanuts specials “It’s the Easter Beagle, Charlie Brown” and “Charlie Brown All Stars,” which posted a 1.3/3 (4.6 million) in the 8 p.m. hour.

NBC’s “The Biggest Loser” (3.1/8, 8 million) showed strong growth throughout the night, posting a 67% increase from the 8 p.m. half-hour to the 9:30 p.m. slot.

At 10 p.m., “Law & Order: SVU” scored a 3.2/9 (9.1 million), winning the 10 p.m. hour.

On CBS, “NCIS” (3.6/10, 17.6 million) was up one-tenth of a point from last week, while both “The Mentalist” (3.6/9, 16.8 million) and “Without a Trace” (2.7/7, 12.2 million) posted dips from last week (down 5% and 4%, respectively).
