NBC on Saturday aired its first Monster Energy NASCAR Cup Series race of the season from Daytona, drawing a 3.0 overnight rating for the Coke Zero 400 from 8:15-11:00pm ET. That figure is down from a 3.2 last year. The race in '15, which was NBC's first year with the new media-rights package, drew a 2.6 overnight, but that race had a three-hour rain delay, forcing the telecast to air from 11:15pm-2:30am. TNT in its final year with the race in '14 drew a 2.4 overnight, but that race aired on a Sunday afternoon due to a rainout on Saturday night. TNT in '13 drew a 3.3 overnight for the summer Daytona race. Austin Karp/SBJ
07/03/17 The NASCAR Coke Zero 400 on NBC Saturday night overnight TV rating was only a 1.0 (Adults only Rating) but the share averaged about 6 with a total of 5.1 million viewers tuned in…..which shows what sort of viewership numbers network TV can deliver compared to what NASCAR has been getting recently on cable TV. In 2016 the rating was 3.4 rating (total viewers) with 5.7 million total viewers on NBC. So the 5.1 million viewers in 2017 represents a drop of 10.6% from last year. More as we get it.
