ncis jan 8 ratings TV ratings: 'NCIS' hits a season high Tuesday while 'Go On' stumblesFast National ratings for Tuesday, Jan. 8, 2013

CBS scored an across-the-board ratings win Tuesday as both “NCIS” and “NCIS: Los Angeles” recorded season bests in total viewers. They also led their respective hours in adults 18-49.

NBC’s 9 p.m. comedies took a tumble without “The Voice” as their lead-in. Both “Go On” and “The New Normal” had their lowest numbers of the season. FOX’s comedies were more or less in line with their season averages.

CBS averaged 16.5 million viewers — more than the other four nets combined — and a 10.4 rating/16 share in households for the night. NBC (5 million, 3.2/5) was the best of the rest, beating ABC (4.2 million, 2.8/4) for second place. FOX came in fourth with 3.2 million viewers and a 2.0/3, while The CW brought in about 940,000 people and a 0.7/1.

The adults 18-49 race was somewhat closer, but CBS still won easily with a 2.7 rating. NBC, 1.7, edged FOX, 1.6, for second. ABC averaged 1.3 in the demographic and The CW 0.3.
