I think you are wrong on that. The reason NASCAR is so big IS because of TV.
NO, NASCAR is because of it's FANS. TV is just exploiting the fan popularity.
That must be true because I do not have tv, the ONLY time I hear about nascar is on this forum. Secondly NEVER in 15 years have any of my friends mentioned, car racing, or nascar in any conversation.
Sorry, sompetative bocci ball is more exciting to watch than NASCAR.
I don't think so. Many of these tracks were around before TV. Also, how would this explain the popularity of local short tracks, and auto racing being the NUMBER ONE spectator sport in the world? Fan interest in auto racing happened long before NBC missed almost every restart for commercial purposes.
