Here's a list of the six industries Steve Jobs revolutionized.
And here's another interesting Apple fact:
When Apple was founded as a partnership in 1976, Ronald Wayne received 10% of the stock but relinquished it for $800 less than two weeks later. Legally, all members of a partnership are personally responsible for any debts incurred by any partner; unlike co-founders Steve Jobs and Steve Wozniak, then 21 and 25, Wayne had personal assets that potential creditors could seize. The failure of a slot machine company that he had started five years earlier also contributed to his decision to exit the partnership.
A 10% stake in Apple today is worth some $40bn.
