Google Inc. (NASDAQ: GOOG) is an American multinational corporation which provides Internet-related products and services, including Internet search, cloud computing, software and  advertising technologies. Advertising revenues from AdWords generate almost all of the  company's profits. The company was founded by Larry Page and Sergey Brin while both attended Stanford University. Together, Brin and Page own about 16 percent of the company's stake. Google was first incorporated as a privately held company on September 4, 1998, and its initial public offering followed on August 19, 2004. The company's mission statement from the outset was "to  organize the world's information and make it universally accessible and useful", and the  company's unofficial slogan is "Don't be evil". In 2006, the company moved to its current headquarters in Mountain View, California. Rapid growth since incorporation has triggered a chain of products, acquisitions, and partnerships beyond the company's core web search engine. The company offers online productivity software including email, an office suite, and social networking. Google's products extend to the desktop as well, with applications for web browsing, organizing & editing photos, and instant messaging. Google leads the development of the Androidmobile operating system, as well as the Google  Chrome OS browser-only operating system, found on specialized netbooks called Chromebooks.
