Google has become the most pop and widely utilized search engines these days. Larry Page and Sergey Brin devised it as a unique project when they were doing Ph.D. during January 1996.

The project was financed and backed up by the Graduate Fellowship of the National Science Foundation.To create the search engine, Larry and Sergey formulated an effective computer language called the Page Rank algorithm.
