2016 was a pivotal year in the 21st century. In June, Britons voted in a referendum to leave the European Union. In November, U.S. voters elected Donald Trump as president, a figure widely regarded as a bad joke by both Democrats and establishment Republicans. Both events marked the beginning of a far-right wave that, a decade later, continues to sweep across much of the world. And both were aided, perhaps decisively, by a small London-based political consultancy: Cambridge Analytica. The company collected data from 87 million Facebook users without their consent and used it to create personalized political propaganda to boost the campaigns for Trump and Brexit, among others.
