(AP) -- NASCAR announced the $2 billion purchase of International Speedway Corp. on Wednesday, an aggressive move to gain control of key racetracks and set itself up for sweeping changes that could save America's most popular racing series.
The deal is expected to close by the end of the year.
ISC owns 12 tracks that host NASCAR races, including Daytona International Speedway, Talladega Superspeedway, Darlington Raceway and Homestead-Miami Speedway. Its holdings stretch from New York to California , and ISC is one of two major facilities companies that host NASCAR races, along with Speedway Motorsports Inc. SMI did not immediately return a message seeking comment on the deal.
