UPDATE: Last Saturday's NASCAR Cup Series playoff race at Richmond (Va.) earned a 1.0 rating and 1.77 million viewers on NBCSN, down 17% in ratings and viewership from last year (1.2, 2.14M) and down 38% and 34% respectively from 2016 (1.6, 2.71M).
Kyle Busch's win ranks as the lowest rated and least-watched NASCAR Cup Series race since at least 2000. The previous lows were a 1.2 (multiple races) and 1.99 million (New Hampshire last year). Six of the ten lowest rated and least-watched races have taken place this season alone.
More races have had less than a 1.5 rating this season than in the previous 17 seasons combined.
