At the age of 21, Steven Jobs was persuaded by his friend Stephen Wozniak to help him create an "insanely great" personal computer that anyone could use. When the stock of their company went public five years later, Jobs made $256.4 million.

After ten years with Apple, Jobs left to start a new computer company, NeXT. He also bought Pixar, Inc., a small computer animation company, from George Lucas. Pixar produced Toy Story, the first feature- length computer animated film, using computers from SGI, Hewlett-Packard, and Sun. When Pixar's stock went public in January 1995, 30-year-old Jobs became a billionaire.

In 1997 Jobs returned to Apple and shortly thereafter assumed the role of CEO, a title he also holds at Pixar. Jobs is credited with the development of the very popular iMac computer.
