Google

Company 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.
