Finally, The Simpsons creator Matt Groening is worth an incredible $600 million (£492m).
Before The Simpsons, the 70-year-old writer, cartoonist and producer was best known for his acclaimed comic strip Life in Hell, which debuted in 1977.
The Simpsons began as a series of animated shorts on The Tracey Ullman Show in 1987. The shorts proved so popular that Fox developed them into a full half-hour series. The first episode, a holiday special titled Simpsons Roasting on an Open Fire, aired in December 1989, with the full first season premiering in January 1990.
While The Simpsons is undoubtedly Groening’s most famous creation, he's also helmed other successful animated shows, most notably Futurama and the Netflix series Disenchantment.
