Facebook co-founder Chris Hughes has called for the breakup of Facebook, the world’s largest social media company. Hughes says the United States has laws to control monopolies: businesses that control too much of an industry. He wants the U.S. government to use those laws to help protect people from technology and social media companies. His comments appeared Thursday in an opinion piece in The New York Times. Facebook Inc. quickly rejected his call. Hughes once shared a room in college with Mark Zuckerberg, who later became Facebook’s chief executive officer. "We are a nation with a tradition of reining in monopolies, no matter how well intentioned the leaders of these companies may be. Mark's power is unprecedented and un-American," Hughes wrote. More than 2 billion people worldwide currently use Facebook. The company also owns WhatsApp, Messenger and Instagram. Each service has more than 1 billion users.
