Is Amazon getting too big?

SAN FRANCISCO – When Amazon made a bid for Whole Foods earlier this month, a company that's been a huge but largely online presence for consumers suddenly seemed to be everywhere, raising the question, "Is it getting too big?" In most of the areas Amazon has recently entered, be they groceries or streaming video or India, Amazon is far from dominant. But some observers fear that as Amazon's breadth grows, the power of its ecosystem could stifle competition and erode jobs. "Imagine getting your pay-TV service, groceries, banking, insurance, etc. all through one company. That's the threat that Amazon poses," said Michael Greeson, director of research at business analysis firm The Diffusion Group.
