Companies like Ford, General Motors, Winston and Gatorade were willing to put up advertising dollars and holding auto races became a much more profitable venture.

[2][3] The following year they partnered with Corning Glass Works to purchase the Watkins Glen International road course in upstate New York.

[8] By this time ISC was profitable, but most of their races were still in the South and in mostly rural areas, with many of the country's major cities like Los Angeles, Detroit, Miami and Chicago lacking a nearby track.

The merger also gave ISC a 90% stake in Homestead-Miami Speedway and the company soon bought out the final 10% to acquire complete control over the track.

On January 28, 2019, it was revealed on ISC's 2018 annual report that a total of 78,000 seats were removed from Chicagoland, Darlington, Kansas, Martinsville, Michigan, Phoenix, and Richmond.

[16][17] ISC and NASCAR made public their desire to have a presence in areas it sees as having the potential for growth, most notably the Pacific Northwest and New York City.

[25] ISC's current proposal was met with a lukewarm response from area lawmakers and citizens, but the company has promised to present an improved offer for early 2007.

[29] In April 2007, this plan was also abandoned by ISC after failing to get their bill out of committee in the Washington State Legislature or to gain the full support of the Kitsap County Commissioners.

[30] On November 30, 2004, the company made no secret of its interest in building a superspeedway in the New York market and was in talks with Staten Island officials about the logistics of constructing a track there.

One report had a local councilman being put in a headlock after one particularly provoking speech (though one ISC official called it merely a "hug for the TV cameras").

[35] Francis Ferko, a stockholder in Speedway Motorsports, Inc., sued NASCAR and ISC in 2002 for violating federal antitrust laws and breach of contract for not awarding a second Winston Cup Series date to Texas Motor Speedway, claiming that the second race was "promised" to the SMI track by NASCAR.

Although NASCAR CEO Brian France initially said he was going to fight the case in the courts, in April 2004 it was announced that the case had been settled out of court with Texas getting the Cup date previously belonging to North Carolina Speedway and, as part of the deal, agreeing to purchase North Carolina—which now had no dates at all—from ISC for $100 million.

[36] NASCAR sought to have the case thrown out by arguing that the speedway wasn't trying to end the alleged anticompetitive practices, they were merely trying to benefit from them as well.

Lawyers for Kentucky Speedway contended that the company does business online and is just as responsible for the lack of competition in granting the races as NASCAR is.

The track is also demanding that NASCAR develop objective standards for the awarding of their race events and damages of $200 million.

[39] In 2011, Kentucky Speedway, now owned by SMI, received a date, the Quaker State 400, on the Cup Series schedule, which lasted until 2020.
