Google Inc is a multinational public cloud computing, Internet search, and advertising technologies corporation. Google hosts and develops a number of Internet-based services and products, and generates profit primarily from advertising through its AdWords program. The company was founded by Larry Page and Sergey Brin, often dubbed the "Google Guys", while the two were attending Stanford University as Ph.D. candidates. It was first incorporated as a privately held company on September 4, 1998, with its initial public offering to follow on August 19, 2004. The company's stated mission from the outset was "to organize the world's information and make it universally accessible and useful", and the company's unofficial slogan – coined by Google engineer Paul Buchheit – is Don't be evil. In 2006, the company moved to their current headquarters in Mountain View, California.
