Facebook was originally named TheFaceBook and it was developed by Harvard student Mark Zuckerberg. The first use of the FaceBook was on the Harvard campus and it was limited only to Harvard students. Soon the FaceBook spread like wild fire around the other major U.S. Universities. Mark Zuckerberg dropped out of Harvard and pursued his facebook dream. It went onto become the 4th most-trafficked website in the world with more than 90 million active users.
