Steven Paul Jobs - Apple

Beginnings of Apple Computer
In the late 1970s, Jobs, with Apple co-founder Steve Wozniak, created one of the first commercially successful personal computers. After losing a power struggle with the board of directors in 1985, Jobs resigned from Apple and founded NeXT, a computer platform development company specializing in the higher education and business markets. In 1996, Apple announced that it would buy NeXT for US$429 million. The deal was finalized in late 1996,[28] bringing Jobs back to the company he founded. With the purchase of NeXT, much of the company's technology found its way into Apple products, notably NeXTSTEP, which evolved into Mac OS X. Under Jobs's guidance the company increased sales significantly with the introduction of the iMac and other new products; since then, appealing designs and powerful branding have worked well for Apple. At the 2000 Macworld Expo, Jobs officially dropped the "interim" modifier from his title at Apple and became permanent CEO.
