The race portion of the 2010 Daytona 500, won by Jamie McMurray, drew a 7.7/16 fast-national rating and 13.3 million viewers on FOX Sunday -- down 16% in ratings and 17% in viewers from last year (9.2, 16.0 mil), and down 25% in ratings and viewership from 2008 (10.2/20, 17.8 mil).
This marks the lowest rated Daytona 500 since 1991 (7.6, CBS), and the least-viewed since 2000 (12.9 mil, CBS).
Overall, Sunday's race ranks as the fourth-lowest rated Daytona 500 since at least '74.
Additionally, the race aired opposite the 2010 Winter Olympics on NBC. The last time the Daytona 500 aired during the Olympics (2006), the race drew an 11.3/23 and 19.4 million viewers. Keep in mind that year's race aired on NBC, which was also carrying the Olympics -- not only helping the Daytona 500 avoid competing with the Winter Games, but also giving the race a major promotional platform.
To put the numbers in perspective, the 2010 Daytona 500 ranks behind the 2009 NBA Finals on ABC (8.4, 14.3 mil), the 2009 World Series on FOX (11.7, 19.3 mil), the 2009 NCAA Final Four on CBS (9.1, 14.9 mil), the final round of The Masters on CBS (8.3, 14.3 mil), and the race portion of the Kentucky Derby on NBC (9.8, 16.3 mil), among others.
