Cambridge Analytics

United Kingdom, 2015. Facebook users around the world are invited to fill out short questionnaires or participate in games and competitions. While filling out these questionnaires, a company accumulates your personal data and outlines your socio-economic profile. That same company, Cambridge Analytics, would later be hired to participate in the Brexit campaign.

The accumulated data made it possible to segment electoral messages through social networks and to convey disinformation about the amounts paid and received.

In March 2018, The Guardian and The New York Times denounced Cambridge Analytics using information from a former employee. The company could not resist the scandal and closed its doors shortly afterwards. Facebook claims it was unaware of the scheme and escapes paying a million-dollar fine.

The United Kingdom's exit from the European Union won by just 2%.

And this was not the only campaign carried out by Cambridge Analytics.
