UPDATE: Sunday’s NASCAR Cup Series race from Michigan averaged a 1.5 rating and 2.51 million viewers on NBCSN, up a tick in ratings and 5% in viewership from last year (1.4, 2.37M) but down 17% and 14% respectively from 2019 (1.8, 2.90M). Keep in mind that last year’s race was the second of a doubleheader weekend at the track, with a Saturday race there pulling a 1.0 and 1.65 million. Starting this year, there is only one Michigan Cup race per season.
Notably, while ratings increased just 4% from last year, the share was up a more substantial 21%. The share is the percentage of households viewing in the average minute out of the number of homes with televisions in use.
