Why Amazon Is About to Become a Force in Online Advertising

Amazon flew under the radar in late June when it announced it was entering the world of advertising by using its consumer data to deliver targeted advertising on third-party sites across the web, but it's big news for online retailers and advertisers. Amazon will now use its huge supply of data to pool consumers into buckets based on the products they looked at or purchased on the retailer's website. The company will help advertisers reach these consumers with targeted media, using behaviorally targeted display ads to drive them to any URL.
