Mark Zuckerberg grew to outrageous fame and fortune when his social media network, Facebook, became the most popular on the internet. With a movie made about him, appearances on several television shows, and his company going public, Zuckerberg became one of the most well-known men in the world. But all of that soon came tumbling down when it was discovered Facebook allowed Cambridge Analytica to take data of 500 million of its users. Facebook’s stock plunged by $50 billion; they’re under investigation by the Federal Trade Commission; and Zuckerberg has appeared before Congress to testify.
