Cambridge Analytica, which is at the centre of a controversy over harvested personal data about Facebook users, on Thursday, released a timeline highlighting its relationship with Global Science Research (GSR) and whistleblower Christopher Wylie.

Aleksandr Kogan, who runs GSR, designed a personality quiz that was taken by a few hundred thousand people but the app on which it ran also collected details about all of their Facebook 'friends' without their knowledge or consent.

That data was then used in a targeted digital ad campaign in support of Donald Trump's successful run for the US presidency, Cambridge Analytica's CEO Alexander Nix told an undercover reporter from Britain's Channel Four news.

Cambridge Analytica's timeline also revealed contractual and legal agreements made in the name of its associated entity, SCL Elections.
