Google is one of the largest websites in the world. It was released to the public on September 4, 1998 by Larry Page and Sergey Brin from a friends garage. Google has a lot of other uses besides being a search engine. There is Google Books, Google Finance, Google Translate, Google Blogs, and much more. On top of owning one of the world's greatest websites, Larry and Sergey also own other non-Google related ( i.e. Google Chrome, Google Maps, Google Docs) websites.
