Over 15 years ago, on February 4, 2004, then-19-year old Harvard student Mark Zuckerberg, along with some of his classmates, launched a little website called the Facebook. "The facebook is an online directory that connects people through social networks at colleges", the original website greeted its visitors back then, explaining that it would enable them to "search for people at your school, find out who are in your classes [sic], look up your friends’ friends and see a visualization of your social network."
