Muhammad Ali, one of the world's most recognized people, has sold 80 percent of the marketing rights to his name and likeness to a firm for $50 million.
The 64-year-old former heavyweight champion, who suffers from Parkinson's disease, will retain a 20 percent interest in the business. The new venture will be operated by a company called G.O.A.T. LLC, an acronym for "The Greatest of All Time."
