Why did Google's Gmail, launched in 2004, scan private correspondence to generate advertising? As soon as the first Gmail user saw the first ad targeted to the content of her private correspondence, public reaction was swift. Many were repelled and outraged; others were confused. As Google chronicler Steven Levy put it, "By serving ads related to content, Google seemed almost to be reveling in the fact that users' privacy was at the mercy of the policies and trustworthiness of the company that owned the servers. And since those ads made profits, Google was making it clear that it would exploit the situation."
