Steve Jobs' contribution

In 1976, Jobs, Steve Wozniak and Ronald Wayne founded Apple. Jobs lured John Sculley away from Pepsi-Cola to serve as Apple's CEO. "Do you want to sell sugar water for the rest of your life, or do you want to come with me and change the world?" At Apple's annual shareholders meeting in 1984, Jobs introduced the Macintosh to a wildly enthusiastic audience. The Macintosh became the first commercially successful small computer with a graphical user interface. The development of the Mac was started by Jef Raskin, and eventually taken over by Jobs. After leaving Apple, Jobs founded NeXT Computer in 1985 with $7 million. In 1996, Apple announced that it would buy NeXT for $429 million. The deal was finalized in late 1996, bringing Jobs back to the company he had co-founded. In August 2011, Jobs resigned as CEO of Apple, but remained at the company as chairman of the company's board. Hours after the announcement, Apple Inc. shares dropped 5% in after-hour trading.
