Facebook's current data crisis involving Cambridge Analytica has angered users and prompted government investigations. To understand what's happening now, you have to look back at Facebook's old policies from 2007 to 2014. Last week, Facebook confirmed that Cambridge Analytica, a data firm hired by President Trump’s campaign, had violated the company’s policies when it purchased the data of 50 million users from a researcher who accessed it in 2013. Facebook asked the data firm and the researcher to certify that the information had been deleted, but it didn’t notify users at the time. In the video above, we take a look at how Facebook’s lax policies of the past regarding the sharing of data paved the way for the company’s current crisis.
