15Matt Groening - $500 million

Net worth: $500 million

The story of Matt Groening, creator of TV's favourite animated family, retaining the merchandising rights to The Simpsons is famous. It's famous because the show went on to have a merchandising career paralleling Star Wars. There are Simpsons EVERYTHING. As a little boy, I had a Bart

wall clock, a poster of all the characters, and slippers of Homer eating donuts. Thing is, I didn't even like The Simpsons that much. With such thorough cultural integration, it's no surprise that Matt Groening would be worth half a billion dollars. That, plus the constant reruns of The Simpsons on every network, plus sales from the season DVDs, means his worth will only continue to snowball.
