Having brought Apple (AAPL) back from the brink of a premature death following his return to the CEO’s office in 1996, Jobs has revolutionized how we consume media of all kinds, whether music, TV shows, and movies. Itunes is now the biggest retailer of music, be it digital or tangibleâ??in the U.S., having sold 5 billion songs as of June. Since 2007 he’s turned his attention to the wireless world, challenging entrenched players like Motorola and Research In Motion with the iPhone.
