UPDATE: Last Sunday's NASCAR Cup Series finale from Homestead earned a 2.5 rating and 4.15 million viewers on NBC, down 11% in ratings and viewership from last year (2.8, 4.66M) and down 29% and 32% respectively from 2016 (3.5, 6.08M).
Joey Logano's Cup-clinching win delivered the lowest rating in the history of the race (dates back to 1999) and the smallest audience since at least 2001. The previous lows were set last year.
As recently as three years ago, the race had a 4.4 rating and 7.6 million viewers on NBC. That year, race coverage bled into NBC's Football Night in America NFL pregame show. Ratings and viewership have declined in each year since.
Homestead completed a rough year for NASCAR. Of the 32 races that were run as scheduled this season, 28 posted a decline in ratings and/or viewership, and 27 hit all-time or decade-plus lows.
