Google

Overview

Google's mission is to organize the world's information and make it universally accessible and useful.

As a first step to fulfilling that mission, Google's founders Larry Page and Sergey Brin developed a new approach to online search that took root in a Stanford University dorm room and quickly spread to information seekers around the globe. Google is now widely recognized as the world's largest search engine -- an easy-to-use free service that usually returns relevant results in a fraction of a second.

When you visit www.google.com or one of the dozens of other Google domains, you'll be able to find information in many different languages; check stock quotes, maps, and news headlines; lookup phonebook listings for every city in the United States; search billions of images and peruse the world's largest archive of Usenet messages -- more than 1 billion posts dating back to 1981.

We also provide ways to access all this information without making a special trip to the Google homepage. The Google Toolbar enables you to conduct a Google search from anywhere on the web. And for those times when you're away from your PC altogether, Google can be used from a number of wireless platforms including WAP and i-mode phones.

Google's utility and ease of use have made it one of the world's best known brands almost entirely through word of mouth from satisfied users. As a business, Google generates revenue by providing advertisers with the opportunity to deliver measurable, cost-effective online advertising that is relevant to the information displayed on any given page. This makes the advertising useful to you as well as to the advertiser placing it. We believe you should know when someone has paid to put a message in front of you, so we always distinguish ads from the search results or other content on a page. We don't sell placement in the search results themselves, or allow people to pay for a higher ranking there.

Thousands of advertisers use our Google AdWords program to promote their products and services on the web with targeted advertising, and we believe AdWords is the largest program of its kind. In addition, thousands of web site managers take advantage of our Google AdSense program to deliver ads relevant to the content on their sites, improving their ability to generate revenue and enhancing the experience for their users.

What's a Google?

"Googol" is the mathematical term for a 1 followed by 100 zeros. The term was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, "Mathematics and the Imagination" by Kasner and James Newman. Google's play on the term reflects the company's mission to organize the immense amount of information available on the web.

History

Google began as a research project in January 1996 by Larry Page and Sergey Brin, two Ph.D. students at Stanford University, California. They hypothesized that a search engine that analyzed the relationships between websites would produce better results than existing techniques, which ranked results according to the number of times the search term appeared on a page. Their search engine was originally nicknamed, "BackRub" because the system checked backlinks to estimate a site's importance. A small search engine called Rankdex was already exploring a similar strategy. Convinced that the pages with the most links to them from other highly relevant web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. Originally the search engine used the Stanford University website with the domain google.stanford.edu. The domain google.com was registered on September 15, 1997, and the company was incorporated as Google Inc. on September 7, 1998 at a friend's garage in Menlo Park, California. The total initial investment raised for the new company eventually amounted to almost $1.1 million, including a $100,000 check by Andy Bechtolsheim, one of the founders of Sun Microsystems.

In March 1998, the company moved into offices in Palo Alto, home to several other noted Silicon Valley technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in Mountain View at 1600 Amphitheatre Parkway from Silicon Graphics (SGI) in 2003. The company has remained at this location ever since, and the complex has since become known as the Googleplex (a play on the word googolplex, a 1 followed by a googol zeros). In 2006, Google bought the property from SGI for $319 million.

The Google search engine attracted a loyal following among the growing number of Internet users, who liked its simple design and usability. In 2000, Google began selling advertisements associated with search keywords. The ads were text-based to maintain an uncluttered page design and to maximize page loading speed. Keywords were sold based on a combination of price bid and clickthroughs, with bidding starting at $.05 per click. This model of selling keyword advertising was pioneered by Goto.com (later renamed Overture Services, before being acquired by Yahoo! and rebranded as Yahoo! Search Marketing). While many of its dot-com rivals failed in the new Internet marketplace, Google quietly rose in stature while generating revenue.

The name "Google" originated from a misspelling of "googol," which refers to 10100 (the number represented by a 1 followed by one-hundred zeros). Having found its way increasingly into everyday language, the verb, "google", was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning, "to use the Google search engine to obtain information on the Internet."

A patent describing part of Google's ranking mechanism (PageRank) was granted on September 4, 2001. The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor.
