Data Cartel

Every search, purchase, and late-night scroll leaves a trace. In 2012, an Austrian law student named Max Schrems asked Facebook to send him a copy of the data it held about him. What arrived was a printed file running to more than 1,200 pages. Messages he believed he had deleted were still there. Locations, timestamps, interactions stretching back years. He had never imagined that his ordinary online activity was being preserved in such detail. Neither had most people. The Data Cartel investigates the hidden industry that made that file possible. It follows personal information through advertising exchanges, data brokerage firms, and analytics platforms that build detailed profiles of millions of people without their knowledge. It examines how companies like Acxiom maintain files on 700 million people worldwide, how a single website can install 223 tracking files on a visitor's computer in a single visit, and how the political consulting firm Cambridge Analytica built psychological profiles of voters from data most users never knowingly shared. Behind the familiar icons on every smartphone screen lies a market where location records, browsing habits, financial behaviour, and private interests are continuously gathered, packaged, and sold. The companies running that market are not household names. But they know a great deal about every household.This is an investigation into the unseen economy of personal data and the power it creates. The question is not whether your digital shadow is being traded. The question is who is profiting from it and whether anyone can be made to stop.
