Could Amazon Go The Way Of Sears Roebuck?

Amazon is the world's largest e-commerce company, but it is trying to be so much more — a mobile carrier, a media company and a major provider of cloud computing services, to name a few.

But is this behemoth internet retailer vulnerable? New York magazine technology columnist Kevin Roose wanted to find out. "Amazon really has unbounded ambitions," Roose told Here & Now's Jeremy Hobson. "What I wanted to find out is how can you take down Amazon?"

In a piece called "6 Ways Competitors Are Trying to Kill Amazon," Roose wrote: "Sears Roebuck withered, in part because it made the mistake of over-­diversification... There’s some evidence that Amazon is overextending itself in similar ways."
