On March 17, The Observer of London and The New York Times announced that Cambridge Analytica, the London-based political and corporate consulting group, had harvested private data from the Facebook profiles of more than 50 million users without their consent. The data was collected through a Facebook-based quiz app called thisisyourdigitallife, created by Aleksandr Kogan, a University of Cambridge psychologist who had requested and gained access to information from 270,000 Facebook members after they had agreed to use the app to undergo a personality test, for which they were paid through Kogan’s company, Global Science Research.
