Google Inc. is an American  multinational public corporation invested in  Internet search,  cloud computing, and  advertising technologies. Google hosts and develops a number of  Internet-based services and products,  and generates profit primarily from  advertising through itsAdWords 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, and itsinitial public offering followed on August 19, 2004. At that time Larry Page, Sergey Brin, and Eric Schmidt agreed to work together at Google for twenty years, until the year 2024.  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.
