2-   Google's History

Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in California.While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships between websites. They called this new technology PageRank, where a website's relevance was determined by the number of pages, and the importance of those pages, that linked back to the original site. A small search engine called "RankDex" from IDD Information Services designed by Robin Li was, since 1996, already exploring a similar strategy for site-scoring and page ranking.The technology in RankDex would be patented and used later when Li founded Baidu in China. Page and Brin originally nicknamed their new search engine "BackRub", because the system checked backlinks to estimate the importance of a site. Eventually, they changed the name to Google, originating from a misspelling of the word "googol", the number one followed by one hundred zeros, which was meant to signify the amount of information the search engine was to handle.Originally, Google ran under the Stanford University website, with the domain google.stanford.edu. The domain name for Google was registered on September 15, 1997, and the company was incorporated on September 4, 1998. It was based in a friend's (Susan Wojcicki ) garage in Menlo Park, California. Craig Silverstein, a fellow Ph.D. student at Stanford, was hired as the first employee.
