Behavioral Targeting and Privacy

Behavioral targeting is a marketing technique where people's online behavior is tracked and the collected information is used to display individually targeted Web advertisements to people.^[1] The captured information encompasses many online activities: the articles people read, the videos they watch, the terms they search for, and so on. Individual profiles can be enriched with mobile device users' up-to-date location data and other data gathered on-and offline. Some email or social network providers analyze the content of private messages for marketing purposes. Vast amounts of information about hundreds of millions of people are collected for behavioral targeting.
