Page and Sergey Brin when they were both PhD students at
Stanford University in California.

History of Google Search Engine


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.

History of Google Search Engine
(continued….)
A small search engine called Rankdex was already exploring a similar
strategy.
 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 google.com was registered on
September 15, 1997, and the company was incorporated on
September 4, 1998, at a friend's garage in Menlo Park, California.
