In an article entitled ‘Can’t Buy Me Love’, Don Bodreaux gives a simple model to value each Beatle:
If each viewer of only The Beatles’ first two “Sullivan” appearances deposited $1 into an account in return for watching The Beatles on these telecasts, this account would have had in it, on Feb. 16, 1964, $143.7 million. If this money had been invested at the historical rate of return earned by U.S. stocks, it would have earned an annual return, on average, of 8 percent. Today, this account would be worth about $4.4 billion.
Divided equally among John, Paul, George and Ringo, Paul’s share today would be $1.1 billion — his approximate current net worth. And this from only a small payment made 45 years ago by each viewer of a mere two episodes of an American television show. [link]
