Sent to me from Gary Price, a presentation on Adwords from the Berkman center: Google’s AdWords system serves ads alongside about a quarter of all web traffic. In the process of serving those ads, Google actively processes the user browsing data in order to target its advertising, making AdWords one of the world’s most extensive processors of personal data. Hal Roberts presents on how Google’s use of the AdWords data seeds a network of grey surveillance that may not have direct effects on the individual surveillance subjects but does have important effects on our modes of creating and consuming content online.
