The world's most exciting, fastest-growing new market is where you least expect it: at the bottom of the pyramid. Collectively, the world's billions of poor people have immense untapped buying power. They represent an enormous opportunity for companies who learn how to serve them. Not only can it be done, it is being done--very profitably. What's more, companies aren't just making money: by serving these markets, they're helping millions of the world's poorest people escape poverty. C.K. Prahalad's global bestseller "The Fortune at the Bottom of the Pyramid" shows why you can't afford to ignore "Bottom of the Pyramid" (BOP) markets.
