CNN reports on the endorsement contracts that lie ahead for Michael Phelps.
His performance in Beijing, where he won a record eight gold medals, puts him in line to earn much more.
"He may be at $30, $40, $50 million a year in endorsements after all this is said and done," said David Harrow of the National Sports Lawyers Association.
Among the 2005 / 2006 top sports earners, Tiger Woods tops the list. It seems a good bet that Michael will be right up there next year.
