The 1970 Motor Trend 500 was a NASCAR Grand National Series (now Sprint Cup Series) event that was held on January 18, 1970 at Riverside International Raceway in Riverside, California. NASCAR's then-humble organization made it affordable for many local, regional, and obscure sponsors to appear on the Grand National Level; including stock car automobile magazines aimed at a small group of hardcore NASCAR fans. Sponsorship today is very expensive for the NASCAR Cup Series and many corporate brands like Kellog's, M&M's and DuPont have scaled back their sponsorship due to recent changes in the American economy.
