There were a ton of fall finales on Tuesday: CBS’ simply did the best. The “NCIS” network edged NBC and ABC in primetime averages among adults 18-49, and crushed them in terms of total viewers. NBC’s post-“Voice” specials let it down, while ABC was not very competitive after “The Conners.”

For the second night in a row, The CW topped Fox reruns with its “Elseworlds” crossover event — Tuesday marked the conclusion of that three-parter. (Last night, Univision also out-rated Fox and Telemundo tied it.)

CBS was first in ratings with a 1.0 rating/5 share in the advertiser-coveted 18-49 demographic and in total viewers with an average of 9.6 million, according to preliminary numbers. The “NCIS” fall finale at 8 landed a 1.3/6 and 12.1 million viewers. At 9, the “FBI” fall finale had a 1.0/4 and 9 million viewers. The “NCIS: New Orleans” fall finale at 10 got a 0.8/4 and 7.7 million viewers.
