One of the top social media websites in the world, Facebook is more than a dot-com and now represents one of the biggest industries in America. Situated in Silicon Valley, California, Facebook was founded by Mark Zuckerberg when he was at Harvard. As the demand for Facebook grew stronger, Zuckerberg started to allow anyone with an email address to set up an account. In 2007, Facebook made Mark Zuckerberg a billionaire. Because it is one of the biggest destinations on the internet, Facebook is a part of several different news headlines, including politics, health, psychology, and breaking news. Facebook makes front-page news headlines often for giving away millions of Facebook shares to charity.
