Sponsorship and broadcasting

Efforts to unify the sponsorship and marketing of all three Triple Crown races began in 1987 when ABC Sports negotiated a deal with Chrysler to pay $5 million to any horse that swept all three races, and $1 million each year there was no Triple Crown sweep to the horse with the highest combined Triple Crown finish. This sponsorship lasted until 1993. The end of the $1 million participation bonus was linked to the breakdown of Prairie Bayou at the Belmont Stakes that year and the uncomfortable situation that arose when the Kentucky Derby winner, Sea Hero, was given the bonus following a seventh-place finish.
