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. "Fascinating... his account of the way in which advertising data collection works is as meticulous as it is accessible, and his presentation of its dangers is illuminating... an eye-opening book." - Kirkus Reviews "It's Hoffman at his caustic best, and leaves the reader in no doubt about why the advertising industry 'desperately needs a makeover.'" - The Independent "A tour de force...it deserves massive readership." - David Wheldon, President Emeritus, World Federation of Advertisers
