The Beatles continue to sell millions of discs, and the New York Supreme Court just cleared the way for the band and its survivors to sue EMI for $25 million in damages and unpaid royalties.
5. Albert Einstein -- The greatest of all super-geniuses has hit a goldmine with the Baby Einstein line of educational videos and toys, which generated $400 million last year. Einstein's estate, controlled by Hebrew University of Jerusalem, gleaned at least $20 million in royalties, more than proving the theory of celebrity relativity.
6. Andy Warhol -- Andy Warhol famously said, "In the future, everyone will be world-famous for 15 minutes." But could the pop icon have ever imagine his art plastered on $200 Levi Strauss jeans, as well as limited edition cell phones, and Adidas running shoes, all to the tune of $19 million?
This winter, Barneys department store will institute the "Happy Warholidays" advertising campaign, with the artist's work on billboards and shopping bags.
New iMac computers are equipped with a feature called Photo Booth, which has a "Warhol" option. Click a button, and the photo of your choice is split into multiple images and candy-colored, just like the artist's classic rendering of Campbell's soup cans. Now, all you have to do is convince a museum that it's modern art.
7. Dr. Seuss -- The Grinch is dreaming of the Great White Way this Christmas. Theodor Geisel's classic children's book is coming to Broadway, with theater unions agreeing to put on 12 shows a week, four more than the industry standard.
The movie version of "How the Grinch Stole Christmas" already proved to be a $260 million blockbuster, so it's not surprising that the good doctor still pulls in $10 million in annual earnings, enough to top Whoville's Who's Who.
The Rest of the list: No. 8, Ray Charles ($10 million); No. 9. Marilyn Monroe ($8 million); No. 10, Johnny Cash ($8 million); No. 11; J.R.R. Tolkien ($7 million), No. 12 George Harrison ($7 million); No. 13. Bob Marley ($7 million).
