This happened on 1985.

1983, Jobs invited john sculley, then CEO of PepsiCo, as CEO of Apple. After Sculley became the CEO of Apple, three new products (Apple Ⅲ, Apple Lisa and Macintosh) launched by Apple suffered fiasco in the market. Jobs believed that Sculley pursued the profit of the product too much, priced the product too high, and finally made the product fail in the market. Sculley believes that Jobs has no idea what business is and what market competition is. So the two often quarrel at the board meeting.

Later, Jobs secretly tried to overthrow Sculley's CEO position, but Sculley knew about it. In the end, Apple's board of directors chose to support Sculley and decided to ban Jobs from all Apple affairs. Although Jobs, as the founder of Apple, is still the chairman of Apple's board of directors, he has been unable to interfere with Sculley's decision.

Because Jobs was a totalitarian and couldn't stand being deprived of power, he finally left Apple on 1985, founded NeXT Company and acquired Pixar Animation Studio.
