After sponsoring the USAC Championship Trail in 1970–1971, Marlboro dropped out of the sport for 1972. After only two seasons as title sponsor, the company became angered when rival Viceroy was signed on to sponsor Vel's Parnelli Jones Racing, at the time dubbed the "super team" of the series. Without any exclusivity clause, managers at Marlboro deemed the situation "impractical and untenable,"[1] and abruptly quit. Marlboro would not return to Indy car racing until 1986.
