Six days after its first race was held, NASCAR was officially incorporated as the National Association for Stock Car Racing, with race promoter Bill France as president. From the beginning, stock car racing had a widespread appeal with its fan base. As the legend goes, the sport evolved from Southern liquor smugglers who souped up their pre-war Fords to outrun the police. NASCAR brought the sport organization and legitimacy. It was Bill France who realized that product identification would increase enthusiasm for the sport. He wanted the fans to see the cars they drove to the track win the races on the track.

By 1949, all the postwar car models had been released, so NASCAR held a 150-mile race at the Charlotte Speedway to introduce its Grand National Division. The race was restricted to late-model strictly stock automobiles. NASCAR held nine Grand National events that year. By the end of the year, it was apparent that the strictly stock cars could not withstand the pounding of the Grand Nationals, so NASCAR drafted rules to govern the changes drivers could make to their cars. Modified stock car racing was born.

Starting in 1953, the major auto makers invested heavily in stock car racing teams, believing that good results on the track would translate into better sales in the showroom. In 1957, rising production costs and tightened NASCAR rules forced the factories out of the sport. Today NASCAR racing is the fastest growing spectator sport in America.
