In the late 1970s, Jobs, with Apple co-founder Steve Wozniak, Mike Markkula, and others, designed, developed, and marketed one of the first commercially successful lines of personal computers, the Apple II series. In the early 1980s, Jobs was among the first to see the commercial potential of the mouse-driven graphical user interface which led to the creation of the Macintosh. After losing a power struggle with the board of directors in 1984, Jobs resigned from Apple and founded NeXT, a computer platform development company specializing in the higher education and business markets. Apple's subsequent 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he has served as its CEO since 1997.
In 1986, he acquired the computer graphics division of Lucasfilm Ltd which was spun off as Pixar Animation Studios. He remained CEO and majority shareholder at 50.1% until its acquisition by The Walt Disney company in 2006. Consequently Jobs became Disney's largest individual shareholder at 7% and a member of Disney's Board of Directors.(Wikipedia)
