Woz, after attending Homebrew meetings on electronics started building his own computer board. Jobs took interest in his work, and on April 1, 1976 started their own computer company at Jobs’ garage in the name of Apple Computer Inc.  Jobs convinced Mike Markkula, a former Intel executive and business man to invest $250,000 in 1977. Thanks to the Apple II, their company could be one of the Fortune 500 in less than two years.

In 1981, Jobs formed a small group of brilliant engineers who made Macintosh possible. And it proved to be big hit.

Steve hired John Sculley, the former Pepsi CEO to have a better market grip in 1983. By early 1985, sales were plummeting, but Steve Jobs refused to acknowledge it and continued to behave as if he had saved Apple. Jobs tried to convince board of directors to fire Sculley, but instead got himself fired.

After getting fired, he founded an animation company by name Pixar, in late 1985. At the time, George Lucas, who was in the middle of an expensive divorce, was selling the computer graphics division of his Lucas film empire. Steve Jobs had millions in the bank, after having sold all his Apple stock, and was interested. In early 1986, he bought the small group of computer scientists, and incorporated it as Pixar, which was a success story.

His next venture was NeXT computer. He built the machine with best hardware, built in the world's best factory and ran on UNIX OS. The machine did good, but not a hit.

In August 1997, Jobs took the stage at Macworld Boston putting forth his plans for Apple. He had gotten rid of the old board of directors, and settled a patent deal with Microsoft for $150 million. One month later, on September 16, 1997, Jobs accepted to become Apple's interim CEO.

Jobs did not turn back since from then; the friendly acquisition of Pixar by Disney, and then series of Apple hit products. Apple was grown into an untamable giant.
