The season finales of “NCIS” and “NCIS: Los Angeles” drove CBS to an across-the-board win in viewers and key demographics on Tuesday.

Meanwhile, NBC’s “America’s Got Talent” improved modestly in viewers, but declined in adults 18-49. A double episode of “Glee” on FOX declined slightly compared to its performance last week.

Overall, CBS had an average of 16.3 million viewers and a 10.3 rating/16 share for the night, ahead of second-place NBC with 8.6 million viewers and 5.3/8 rating by a wide margin. ABC came in third with 7.8 million viewers and 5.3/8.

CBS experienced its best Tuesday deliveries in viewers since February and its best adult 18-49 delivery on a Tuesday night since January. CBS finales topped both Monday and Tuesday this week in adults 25-54 and 18-49.

CBS also won the adult 18-49 demographic with a 3.2 rating, followed by NBC at 2.8 and FOX at 2.5. ABC had a 1.7, while The CW scored merely 0.4.

CBS’s “NCIS: Los Angeles,” now in its third season, combines elements of police procedural genres and military drama. The series airs after “NCIS” on Tuesdays.
