According to The Register (citing a paywalled WSJ article
), a new face in targeted ads is emerging (according to "people familiar with the matter") to compete with Google, and it's Amazon
. They already have a vast, mineable collection of data about customers' buying, listening and viewing habits, so exploiting personalized ads seems a natural follow-on. According to the report, the ad system would replace Google as ad vendor on Amazon itself, and "It is also apparently hoping to beef up its ad placement business on other sites as part of Amazon's strategy to carve its way into Google's multi-billion-dollar AdWords' empire." Pretty soon Amazon will able to just save me time by ordering the things I would have ordered based on ads that they themselves have placed.
