ESPN said its live broadcast of the Royal Purple 300 NASCAR Nationwide Series race at Auto Club Speedway on March 26 earned a final national household coverage rating of 1.6, averaging 2,148,001 viewers, according to the Nielsen Company.
The race has no direct comparison to 2010 because it was moved to a different date. However, ESPN says the race held at Nashville Superspeedway in the same time frame last year earned a 1.1 rating on ESPN.
And in 2010, the Fontana race that was held in February earned a 1.7 rating on ESPN2.
Overall, the combined network average U.S. rating for the Nationwide Series so far this season is a 1.7, the same as it was at this point in both 2009 and 2010.
