#4 Moving the sport away from Winston sponsorship.
Believe it or not, Brian France has always sought to bring the youth movement to NASCAR even in his early days. In fact, France was the one that moved the sport away from longtime series sponsor, Winston Cigarettes, which allowed the sport to start marketing to a younger demographic when he was head of the marketing department.
Although this was a controversial move at first, especially after how long Winston had served as the title sponsor, the moved allowed the sport to add a whole new demographic to their fan base and also made the sport more marketable overall in the process. If nothing else, Brian France is largely responsible for the sport being able to move forward after advertising for cigarettes became controversial.
