Can you imagine that the most popular search engine in the world was once called "BackRub"? Though it sounds quite strange this is simple truth. Larry Page and Sergey Brin called it so when they just started to work on it at Stanford University. Later, when the browser became too large, the creators made a wise decision to rename it. By the way, the name Google is derived from the mathematical term "googol" which denotes the number 1 plus 100 zeros!
