An organiser of the World's information, I guess.

Named for the mathematical term "googol," Google operates web sites at many international domains, with the most trafficked being www.google.com. Google is widely recognized as the "world's best search engine" because it is fast, accurate and easy to use.

Google's breakthrough technology and continued innovation serve the company's mission of "organizing the world's information and making it universally accessible and useful."
