When Steve Jobs left Apple and founded NeXT Computer, his targeted markets were the institutions such as school’s research centers. Its been said that he talked to countless institutions and asked the professors about their needs.
His market research seemed to indicate that they need a more powerful workstation. He even got Standard University to take a partial share in his company.
We know that Steve is famous for relying on his instincts to come out with new ideas. But this is a case where he actually did a lot of research such as checking on the needs of his targeted markets.
But as you know, he failed miserably with NeXT Computer. Market research is something that he did not need.
