Season finale, special win primetime ratings

The season finale of “Law & Order: SVU” drew both the top rating and most eyeballs Tuesday night, giving NBC a rare primetime win. The Peacock also fared well with its “Inside the Obama White House” special hosted by Brian Williams, where viewers got a look at the day in the life of the new president and the staff who work with him.

CBS came in second with repeats of some of its top procedurals, plus a new installment of “48 Hours.” Fox saw disappointing numbers for the second week of “Mental,” which dropped significantly and doesn’t look to be a longtime player on the schedule.

The second installment of “The Tonight Show With Conan O’Brien,” where Tom Hanks guested and Green Day performed, averaged a 5.0/12 in metered-market households, the highest overnight rating for a Tuesday “Tonight Show” in more than two years. That’s down 30% from Monday’s launch, when “Conan” earned a 7.1/17.

According to preliminary nationals from Nielsen, “Law & Order: SVU” (3.4 rating/9 share in the 18-49 demo, 11.3 million viewers), the most popular series of the “L&O” franchise, scored its biggest audience in more than a year. “Inside the Obama White House” (2.6/7, 9.1m), which airs its second hour at 9 p.m. tonight, won the hour Tuesday over “The Mentalist” (2.3/7, 10.8m).

“I’m a Celebrity … Get Me Out of Here” (2.1/7, 5.4m) fell 20% from its premiere on Monday in the demo and lost 1 million viewers. Despite the drop-off, “Celebrity” tied “NCIS” (2.1/7, 11.1m) but fell far short of viewers compared to “NCIS.”

ABC failed to get much traction from two-hour special “Earth 2100” (1.2/3, 3.7m).

Preliminary 18-49 averages for the night: NBC, 2.7/8; CBS, 2.1/6; Fox, 1.5/5; Univision, 1.5/4; ABC, 1.2/4; CW, 0.6/2.

In total viewers: CBS, 9.9 million; NBC, 8.6 million; Fox, 4.5 million; ABC, 3.8 millon; Univision, 3.7 million; CW, 1.6 million.
