International Speedway Corporation (ISC) is a corporation whose primary business is the ownership and management of NASCAR and IndyCar race tracks.
 ISC was founded by NASCAR founder Bill France, Sr. in 1953 for the construction of Daytona International Speedway and in 1999 they merged with Penske Motorsports to become one of the largest motorsports companies in North America.
 The company has played an important, though controversial, role in the modernization of the sport.
