What exactly does it mean that Amazon’s Jeff Bezos has purchased the Washington Post?

Business Insider‘s Henry Blodget takes a stab at an explanation:

Given Amazon’s expertise in affiliate marketing and advertising, it’s not hard to imagine that the Washington Post could quickly become a laboratory for the next generation of integrated content and commerce.

Of course, Bezos is an investor in Business Insider, so for a possibly less biased take (complete with a bizarrely unflattering stock photo of Bezos), here’s Forbes contributor Greg Satell:

For decades there has been precisely two business models for media: Advertising and subscription. Today, we’re seeing a third one emerge, content as a promotional tool…e-commerce is starting to play the role once solely reserved for advertising, monetizing content through promoting the sale of products and services.”
