Steve Jobs Was Deeply Influenced by Clayton Christensen's "The Innovator's Dilemma"
(p. 408) Microsoft was willing to license its Windows Media software and digital rights format to other companies, just as it had licensed out its operating system in the 1980s. Jobs, on the other hand, would not license out Apple's FairPlay to other device makers; it worked only on an iPod. Nor would he allow other online stores to sell songs for use on iPods. A variety of experts said this would eventually cause Apple to lose market share, as it did in the computer wars of the 1980s. "If Apple continues to rely on a proprietary architecture," the Harvard Business School professor Clayton Christensen told Wired, "the iPod will likely become a niche product." (Other than in this case, Christensen was one of the world's most insightful business analysts, and Jobs was deeply (p. 409) influenced by his book The Innovator's Dilemma.) Bill Gates made the same argument. "There's nothing unique about music," he said. "This story has played out on the PC."
