Everywhere we go on the web we are being followed. Everything we do on the web is being catalogued. This is called tracking. Tracking is just a pleasanter word for spying. By tracking us, marketers know who we talk to, what we say, where we go, and what we do. They know who our friends are, what our interests are, what our bank balances look like, what our sexual preferences are, what our political leanings are, and where we are at any moment. The consequences of all this surveillance have become shocking, disturbing, and dangerous. In ADSCAM , Bob Hoffman follows his #1 selling book BadMen to describe how online tracking has become a threat to individuals and to democratic societies, and has helped create one of the greatest frauds in history. "A fascinating account of an advertising practice little understood...as meticulous as it is accessible ...this is an eye-opening book." - Kirkus Reviews
