||[url=http://google.com]Google[/url] 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 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 PhD candidates. It was first incorporated as a privately held company on September 4, 1998, and its initial 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 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 – coined by Google engineer Amit Patel and supported by Paul Buchheit – is "Don't be evil". In 2006, the company moved to its current headquarters in Mountain View, California.
It has been estimated that Google runs over one million servers in data centers around the world, and processes over one billion search requests and about twenty-four petabytes of user-generated data every day. Google's rapid growth since its incorporation has triggered a chain of products, acquisitions, and partnerships beyond the company's core web search engine. The company offers online productivity software, such as its Gmail email service, and social networking tools, including Orkut and, more recently, Google Buzz and Google+. Google's products extend to the desktop as well, with applications such as the web browser Google Chrome, the Picasa photo organization and editing software, and the Google Talk instant messaging application. Notably, Google leads the development of the Android mobile operating system, used on a number of phones such as the Nexus One and Motorola Droid, as well as Google Chrome OS, which is brand new (was just released on June 15, 2011) but is best known as the main operating system on the Cr-48 and also on commercial Chromebooks since June 15, among them the Samsung Series 5 and Acer AC700 Alexa lists the main U.S.-focused google.com site as the Internet's most visited website, and numerous international Google sites (google.co.in, google.co.uk etc.) are in the top hundred, as are several other Google-owned sites such as YouTube, Blogger, and Orkut. Google also ranks number two in the BrandZ brand equity database. The dominant market position of Google's services has led to criticism of the company over issues including privacy, copyright, and censorship.
