While measuring the success of broadcast series has largely been a job for the TV ratings among the advertiser-coveted adults 18-49 demographic, that total viewer tally is still powerful and not to be ignored.

With the end of the 2021-2022 season fast approaching, Variety has looked at 33 weeks of complete Nielsen data from September to May to assess what the most and least-watched primetime scripted series have been across NBC, ABC, CBS and Fox.

The below total viewer averages are season-long for each show and include persons over the age of 2, which is what Nielsen counts as a viewer. The totals are based on Nielsen’s “most current” data stream through May 8, which includes a week’s worth of delayed viewing where available.

For the “most” list, it is ranked beginning with the top show. For the “least” list, it starts with the weakest in the top slot and goes up from there.
