The buying and selling of brand name athletes, is common but is the deal worth it. Muhammed Ali in 2005, name was sold to CKYinc at the time for 50 million dollars, with 20% going to Ali and his family and himself. Not mentioned in that deal to the public, is that for the 20% Ali appearances has to made, long flight travels. The devil is in the details, that most of the public may never know.
How else to explain that George Foreman's brand is worth twice that of Muhammad Ali, the greatest boxer of all time? and Foreman sold his rights for 137.5m Or that Jennifer Lopez can outshine Marilyn Monroe in earnings power, with only a fraction of the star power? Money is a measure that crosses boundaries too. Michael Jordan can outdraw Paris Hilton and even Albert Einstein. But when it comes to Elvis Presley, even His Airness is grounded by the King.
Calculating the value of celebrity names can be tricky. While some stars cut straightforward deals in which the figures become public, many others have complex, multi-year deals and keep the details secret. Mike Tyson has sold his name and the details has been kept secret even to me, they have even removed content from the internet to keep it hidden.
