The name "Google" is a play on the word "googol." The creators of Google, Sergey Brin and Larry Page, came up with the name for what would become the largest search engine on the Internet.
Googol is a mathematical term for a specific number that is written out as the numeral 1 followed by 100 zeros. According to Brin and Page, the theory behind selecting a name based on this extremely large number is to reflect the mission of Google to organize a potentially infinite amount of information on the Internet. Google.com was registered as a domain name on Sept. 15, 1997.
When the founders decided to register the name with the Internet, graduate student Sean Anderson did not spell "googol" correctly, and it came out as "google," according to Stanford University. Both of the company's founders liked the idea, and the domain was registered on Sept. 15, 1997. The original name for Google was "BackRub" because of the back links the search engine peruses.
Google was started as an algorithm that searches web pages and their associated links rather than which pages are getting the most traffic. The mission of Google is to "organize the world's information and make it universally accessible and useful," according to Penn State University.
Google has grown into dozens of products including email, maps, voicemail, social networking, mobile operating systems and video sharing services. Google is one of the world's leading web portals and search engines in terms of usage and advertising revenue.
