Steve Jobs, left, John Sculley, president and CEO of Apple, and Steve Wozniak unveil the new Apple IIc computer in San Francisco on April 24, 1984. About a year after this photo was taken, the leadership of Apple would undergo a massive shift. Wozniak had left the company once from 1981-1983, but left for good in February 1985 to start another firm called CL-9. Meanwhile, the once close bond between Sculley and Jobs was starting to fracture. The pair became involved in a power struggle, with Sculley concerned that Jobs didn't have the right vision for the company's operations. Jobs's role at the company was minimalized, a move he deeply resented. In fact, he later compared it to a punch in the gut. Jobs resigned in 1985 over the matter. He was just 30 at the time.
