About NASCAR

The National Association for Stock Car Auto Racing, Inc. (NASCAR), which began in 1948, is the sanctioning body for one of America’s premier sports. NASCAR is the No. 1 spectator sport – holding 17 of the top 20 attended sporting events in the U.S., the No. 2–rated regular season sport on television with broadcasts in more than 150 countries, and has 75 million fans that purchase more than $2.1 billion in annual licensed product sales. These fans are the most brand loyal in all of sports and as a result, more Fortune 500 companies participate in NASCAR than any other sport. NASCAR consists of three major national series (NASCAR NEXTEL Cup Series, NASCAR Busch Series, and the NASCAR Craftsman Truck Series) as well as eight regional tours and one local grassroots series. NASCAR sanctions 1,500 races at over 100 tracks in 35 states, Canada and Mexico. Based in Daytona Beach, NASCAR has offices in Bentonville (Ark.), Charlotte, Concord (N.C.), Conover (N.C.), Los Angeles, New York, Mexico City and Toronto.
