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 the Harvard and pursued his facebook dream to become one of the 4th most-trafficked websites in the world with more than 90 million active users. The FaceBook website is built on PHP-MySQL technology and it is probably the most popular PHP website ever built. Interesting fact is that the facebook.com domain was purchased for $200,000 and FaceBook has more than 24 million photos uploaded daily.
