“What we're now starting to see, as online retailers begin to capitalize on their extraordinary economic efficiences, is the shape of a massive mountain of choice emerging where before there was just a peak.... By necessity, the conomics of traditional, hit-driven retail limit choice. When you dramatically lower the costs of connecting supply and demand, it changes not just the numbers, but the entire nature of the market. This is not just a quantiative change, but a qualitative one, too. Bringing niches within reach reveals latent demand for noncommercial content. Then, as demand shifts toward the niches, the economics of provided them improve further, and so on, creating a positive feedback loop that will transform entire industries - and the culture - for decades to come.”
