NASCAR racing is big business. Racing teams require over $15 million a year to keep their cars in competition. Primary sponsors of teams, like Mooresville-based Lowe's, pay up to $10 million a season, and secondary sponsors pay up to $1 million. In return, the sponsors get their logos displayed on the racing cars and the drivers' outfits. Sponsors believe the money is a good advertising investment since the thirty-six NASCAR Nextel Cup races attract over thirteen million fans, besides the 200 million who view the four-hour races on television.
