To be able to do this, retailers need companies that can provide rich data about our lives. That’s where a group of pioneering companies in the new universe of customer surveillance called data aggregators come in.

Then they analyze, package, and sell it to third parties. “Our digital reach,” said Scott Howe, CEO of the largest data aggregator, Acxiom, “will soon approach nearly every Internet user in the U.S.”
