Obviously, Toyota is not the only company that sees sports as a powerful way to reach and influence current and potential customers. Sports and business are so enmeshed it's hard to believe golfers like Tiger Woods and tennis stars like Serena Williams ever played in shirts without corporate logos. We only vaguely remember when the Orange Bowl was just that, instead of the FedEx Orange Bowl, or when the L.A. Lakers played in the Forum instead of Staples Center, or the Seattle Mariners' diamond wasn't set in Safeco Field. In all, more than $6 billion was spent on athletic sponsorships of varying types in 2003, according to the consultancy A.T. Kearney. And each year, that number grows by about nine percent.

Kathleen Joyce, the editorial director of Promo magazine, a Connecticut-based publication that covers the promotional­ marketing industry, believes com­panies are simply trying to tap into a driving force in American culture. "The cult of celebrity is so powerful, whether you're talking about Hollywood personalities, political personalities, or sports personalities, that brands are trying to borrow whatever equity they can from these people to make themselves relevant to the audiences that follow those celebrities," she says. "For brands, it boils down to what enhances your relationship to the consumer and what brings you new consumers."

Joyce points to NASCAR as one of the most compelling examples of why companies look to be associated with sports. Its ­devoted fans, she says, make corporate sponsors salivate - and write big checks. "If you can find a way to transfer or borrow some of the loyalty fans feel toward ­NASCAR and its drivers," she says, "if you can attach some of that to your own brand, there's a very significant financial value to that."
