CNBC: If there's one indisputable truth about retailing on the Internet, it's that the established retail cliques have consistently underestimated how it would grow. That's allowed the new wave of entrepreneurs, led by Jeff Bezos of Amazon and Pierre Omidyar of Ebay, to break into mature markets where they theoretically had no right to become established, and build that foothold into positions where much longer-established retail rivals operate in fear of them.
