While in a virtual dead-heat with NBC for overall total reach, the ViacomCBS-owned network averaged 6.32 million viewers in the highly valued 8-11 Pm period for the 2019-2020 full-year season, says Nielsen. To put that in another perspective, CBS beat the Comcast-owned network by 723,000 sets of eyeballs in primetime, according to data spanning from September 23, 2019-September 13, 2020.
That primetime win for CBS was in no small part thanks to NCIS. The 20-episode 17th season of the Mark Harmon-led procedural snared an average audience of 15.3 million, making it the most watched series on the small screen. The most watched show on primetime last season was NBC’s flagship NFL show Sunday Night Football, which averaged 20 million viewers.
In total reach for the full year, Nielsen says NBC averaged 228.2 million viewers across all dayparts.
