History of creation
The considered American search enginewas created by Sergei Brin and Larry Page in 1996. Originally it was a student project, when its founders were trained at Stanford University. It was based on the idea that a mathematical algorithm for analyzing user relationships with websites would be more practical than a conventional text search. The result of the student project was the creation of Google Inc in 1998. Her headquarters were in the state of California (Menlo Park). Soon after, the American Internet search engine Google with the same name of its site appeared on the Internet.
In February 1999, the company headquarters wasmoved to Palo Alto, California. Given the growing interest in finding information and increasing profits from contextual advertising on the Internet, the founders were able to hire a professional team of employees. The new headquarters began to be called Googleplex. At the initial stage, Google's main competitor was Microsoft's search engine.
