There are motorsports, and then there's NASCAR. NASCAR has evolved into an industry, with 75 million fans who tune in and travel in throngs to watch stock car racing, identifying with drivers and their favorite front-engine, rear-wheel-drive V8s. NASCAR started off as a sport for the boys in 1948, but somewhere along the way, things changed. NASCAR reports that 40 percent of these 75 million fans are women. For women, NASCAR is the second-most-watched television sport, following football, according to Fox Sports Network.
