Facebook was originally named TheFaceBook and, developed by Harvard student Mark Zuckerberg, was limited only to Harvard students. Now it is the 4th most-trafficked websites in the world with more than 90 million active users. The FaceBook website is built on PHP-MySQL technology, the same technology that underpins all Toucan Internets advanced websites, and it is probably the most popular PHP website ever built. FaceBook has more than 24 million photos uploaded daily.
