Last year, money spent on sports marketing was estimated at $10 billion. That includes things like stadium rights and NASCAR sponsorships. Nearly 10 percent of that money came from banks and other financial services companies. But in light of bailouts and billion dollar losses, these companies are under intense scrutiny. And as a result, banks say they're walking away from money-making deals, just to avoid the controversy. No company is more prominent in the world of sports than Bank of America. Its home city of Charlotte is a perfect example. It spent $44 million on sporting event last year, including NASCAR's Bank of America 500.
