Google began in January 1996 as a research project by Larry Page and Sergey Brin, when both were Ph.D. students at Stanford University, California, United States .
While conventional search engines display results sorted by counting how many times the search terms appeared on the front page, the two theorized about a better system that analyzed the relationships between the sites. They called this new technology PageRank, where relevance of a site was determined by the number of pages, as well as the importance of those pages that linked back to the original site.
A small search engine called “RankDex” of IDD Information Services, designed by Robin Li, since 1996, was already exploring a similar strategy for scoring and ranking pages (text with images). The technology was patented RankDex and later used by Li, when he founded Baidu in China.
Page and Brin originally dubbed its new search tool “backrub”, because the system checked back links to estimate the importance of a site.
Eventually, they changed the name to Google, from a misspelling of the word “googol,” the number one followed by one hundred zeroes, which was created to indicate the amount of information the search engine could process. Originally, Google ran under the site of Stanford University, with the domain google.stanford.edu .
The domain name “Google” was registered on September 15, 1997 and the company was incorporated on September 4, 1998. At first, his seat was in the garage of a friend (Susan Wojcicki ) in Menlo Park, California. Craig Silverstein, a fellow doctoral student at Stanford, was hired as the first official.
