Google Inc. is an American public corporation, earning revenue from advertising related to its Internet search, e-mail, online mapping, office productivity, social networking, and video sharing services as well as selling advertising-free versions of the same technologies. Google has also developed an open source web browser and a mobile operating system. The Google headquarters, the Googleplex, is located in Mountain View, California. As of March 31, 2009, the company has 19,786 full-time employees. The company is running millions of servers worldwide, which process about 1 petabyte of user-generated data every hour. Google conducts hundreds of millions of search requests every day.
Google was founded by Larry Page and Sergey Brin while they were students at Stanford University and the company was first incorporated as a privately held company on September 4, 1998. The initial public offering took place on August 19, 2004, raising $1.67 billion, implying a value for the entire corporation of $23 billion. Google has continued its growth through a series of new product developments, acquisitions, and partnerships. Environmentalism, philanthropy and positive employee relations have been important tenets during the growth of Google. The company has been identified multiple times as Fortune Magazine's #1 Best Place to Work, and as the most powerful brand in the world (according to the Millward Brown Group).
Google's mission is "to organize the world's information and make it universally accessible and useful". The unofficial company slogan, coined by former employee and Gmail's first engineer[8] Paul Buchheit, is "Don't be evil".Criticism of Google includes concerns regarding the privacy of personal information, copyright, and censorship.
Advertising
99% of Google's revenue is derived from its advertising programs. For the 2006 fiscal year, the company reported $10.492 billion in total advertising revenues and only $112 million in licensing and other revenues. Google is able to precisely track users' interests across affiliated sites using DoubleClick technology and Google Analytics. Google's advertisements carry a lower price tag when their human ad-rating team working around the world believes the ads improve the company's user experience.Google AdWords allows Web advertisers to display advertisements in Google's search results and the Google Content Network, through either a cost-per-click or cost-per-view scheme.[citation needed] Google AdSense website owners can also display adverts on their own site, and earn money every time ads are clicked.[citation needed] Google began in March 2009 to use behavioral targeting based on users' interests.
Google has also been criticized by advertisers regarding its inability to combat click fraud, when a person or automated script is used to generate a charge on an advertisement without really having an interest in the product. Industry reports in 2006 claim that approximately 14 to 20 percent of clicks were in fact fraudulent or invalid.
In June 2008, Google reached an advertising agreement with Yahoo!, which would have allowed Yahoo! to feature Google advertisements on their web pages. The alliance between the two companies was never completely realized due to antitrust concerns by the U.S. Department of Justice. As a result, Google pulled out of the deal in November, 2008.
Software
The Google web search engine is the company's most popular service. As of August 2007, Google is the most used search engine on the web with a 53.6% market share, ahead of Yahoo! (19.9%) and Live Search (12.9%). Google indexes billions of Web pages, so that users can search for the information they desire, through the use of keywords and operators, although at any given time it will only return a maximum of 1,000 results for any specific search query. Google has also employed the Web Search technology into other search services, including Image Search, Google News, the price comparison site Google Product Search, the interactive Usenet archive Google Groups, Google Maps, and more.
In early 2006, the company launched Google Video, which allowed users to both upload videos, and search and watch videos from the larger Internet. In 2009 uploads to Google video were discontinued.
Google has also developed several desktop applications, including Google Desktop, Picasa, SketchUp and Google Earth, an interactive mapping program powered by satellite and aerial imagery that covers the vast majority of the planet. Many major cities have such detailed images that one can zoom in close enough to see vehicles and pedestrians clearly. Consequently, there have been some concerns about national security implications; contention is that the software can be used to pinpoint with near-precision accuracy the physical location of critical infrastructure, commercial and residential buildings, bases, government agencies, and so on. However, the satellite images are not necessarily frequently updated, and all of them are available at no charge through other products and even government sources; the software simply makes accessing the information easier. A number of Indian state governments have raised concerns about the security risks posed by geographic details provided by Google Earth's satellite imaging.
Google has promoted their products in various ways. In London, Google Space was set-up in Heathrow Airport, showcasing several products, including Gmail, Google Earth and Picasa. Also, a similar page was launched for American college students, under the name College Life, Powered by Google.
In 2007, some reports surfaced that Google was planning the release of its own mobile phone, possibly a competitor to Apple's iPhone. The project, called Android, an operating system provides a standard development kit that will allow any "Android" phone to run software developed for the Android SDK, no matter the phone manufacturer. In September 2008, T-Mobile released the first phone running the Android platform, the G1.
Google Translate aka Google Language Tools is a server-side machine translation service, which can translate 35 different languages to each other, forming 595 language pairs. Browser extension tools (such as Firefox extensions) allow for easy access to Google Translate from the browser. The software uses corpus linguistics techniques from translated documents, (such as United Nations documents,[citation needed] which are professionally translated) to extract translations accurate up to 88 percent. A "suggest a better translation" feature appears with the original language text in a pop-up text field, allowing users to indicate where the current translation is incorrect or else inferior to another translation.
On 1 September 2008, Google pre-announced the upcoming availability of Google Chrome, an open-source web browser, which was released on 2 September 2008.
On 7 July 2009, Google announced the project to develop Google Chrome OS, an open-source Linux-based operating system in a "window of opportunity"
