International Speedway Corporation

The corporation owns California Speedway , Darlington Raceway , Daytona International Speedway , Homestead-Miami Speedway , Kansas Speedway , Martinsville Speedway , Michigan International Speedway , Phoenix International Raceway , Richmond International Raceway , Talladega Superspeedway , and the Watkins Glen International road course and owns a minority interest in Chicagoland Speedway . Together these tracks hold slightly less than two-thirds of the events on the NASCAR Nextel Cup Series schedule. ISC has also agreed to purchase 600 acres (2.4 km²) on Staten Island in New York for the construction of a new speedway.

In 2005, Kentucky Speedway filed a lawsuit against ISC and NASCAR, claiming that NASCAR violated federal antitrust laws by not awarding them a Nextel Cup race, noting the close relationship between NASCAR, ISC, and the France Family.

The company's other holdings include the Motor Racing Network, a radio network that broadcasts NASCAR events, Americrown, a food service business that operates concession stands at its tracks, and DAYTONA USA , an attraction just outside Daytona International Speedway. In 2006, ISC partnered with Speedway Motorsports, Inc. to form Motorsports Authentics, a company that markets and distributes NASCAR-related souvenirs and collectibles.
