We’ve all heard its origin story. Facebook, originally TheFacebook, was started in 2004 by Mark Zuckerberg and some of his Harvard classmates as a social site for the school alone. It was a big hit, of course, and suddenly other campuses wanted in. Over time, more and more schools were granted use of the platform, and soon certain businesses were allowed to use it as well. Then, in September 2006, Facebook opened its digital doors to any and all users (as long as they were over 13).
