2013: ThisIsYourDigitalLife
Cambridge academic Aleksandr Kogan, from Global Science Research, launched a Facebook app that took the form of a personality quiz. Around 300,000 users completed the test, providing Kogan with access not only to their personal data but that of perhaps millions of their friends.
2014: Facebook changes the rules
In 2014, Facebook closed the loophole that Kogan had exploited and created new limits in the ways developers could access users’ personal data. Nevertheless Kogan retained the data he had collected, which found its way into the hands of GSR’s sister company Cambridge Analytica.
2015: Cambridge Analytica and Ted Cruz
Presidential hopeful Ted Cruz began using, according to a report in the Guardian, research company Cambridge Analytica to determine the voting intentions of million of Facebook users. In response to the story, Facebook requested that all of Kogan’s original data was deleted.

March 21 2018: Zuckerberg issues first public comment
The Facebook founder issued a long public post on his website, which began “I want to share an update on the Cambridge Analytica situation -- including the steps we've already taken and our next steps to address this important issue.”
After outlining new, simplified privacy tools he concludes “While this specific issue involving Cambridge Analytica should no longer happen with new apps today, that doesn't change what happened in the past.”
He later spoke to the New York Times, saying that Facebook would "dramatically reduce the amount of data that developers have access to" and "do a full forensic audit" of all apps that "have any suspicious activity".
March 25 2018: The newspaper ads
Facebook paid for a number of full-page adverts in several leading English-language newspapers apologising for the data breach issues. Signed by Zuckerberg, they read “I'm sorry we didn't do more at the time. We're now taking steps to ensure this doesn't happen again.”
Now – The testimony
Mark Zuckerberg is currently testifying to a senate committee.The hearing is dismissed by many commentators as a sham with Zuckerberg’s responses to questions brief and unrevealing.
Zuckerberg maintains that Kogan and Cambridge Analytica misused or improperly obtained facebook data.
In his second day opening statement, Democratic senator Frank Pallone warned: “For all the good it brings, Facebook can be a weapon for groups like Russia and Cambridge Analytica.”
