Origins and Evolution

Google was founded in 1998 by Larry Page and Sergey Brin, two Ph.D. students at Stanford University. Their initial goal was to develop a search engine that would sort and rank web pages based on their relevance to user queries. Named BackRub, the search engine later evolved into Google, a play on the mathematical term "googol," which represents the number 1 followed by 100 zeros.
