Where were you when news of the tsunami hit Japan in 2011? How about when Michael Jackson died? Probably online, according to many experts who claim that social media has become the main media source for hundreds of millions of people. Not just in the U.S., either; Facebook alone has more than 900 million users spread across the globe as of 2012. Other social media giants like Twitter have facilitated revolution against unjust leaders and warned people of impending natural disaster. In fact, so many people regularly interact online that if the Internet were a nation, it would exceed the Americas, Europe and the Middle East combined in population. No wonder more than 13 million members of the online community used Reddit and other media platforms to protest S.O.P.A., a proposed Internet censorship bill.
