Steve Jobs recruited John Sculley from President at Pepsi (which he had joined in 1963) on the infamous quote that did Sculley want to sell sugar water all his life, or join Jobs and change the world? Sculley had been famous for developing 'The Pepsi Challenge' 1975 taste-test campaign.
That was 1983 and they became best friends describing it as an "amazing partnership". In 1984, there was the famous Superbowl commercial, "1984" (ironically).
Eventually Jobs believed Sculley was "bad for Apple" and a power struggle culminated in a Board showdown in May 1985. Having been best friends, they were now best enemies.
The Board sided with Sculley and 5 months later, Jobs resigned from Apple. Of course in 1986 he started Pixar and in 1995 produced their first feature, 'Toy Story'. Jobs was the Executive Producer.
In 1996 Jobs rejoined Apple and the rest, as they say, is history. Sculley had left/fired in 1993.
It's pretty clear that the clash was between an innovator and a business head. Sculley was focused on structure, cashflow and traditional business whilst Jobs was just an unruly doer. Jobs, it has to be said, was no angel either.
And Sculley has never talked about it...until this week aged 74. Worth a look.
And then at the very,very end of this piece - hear Jobs talking about Sculley - "I hired the wrong guy.....he destroyed everything I'd spent 10 years working for...starting with me"
