Sergey Brin:  At Google, our mission is to make the world’s information accessible and useful. And that means all of the world’s information, which now, in our index, numbers over a billion documents, and it’s an incredible resource. In history, you have never had access to just pretty much all of the world’s information in seconds, and we have that now, and to make it really useful, you have to have a good way of finding whatever it is that you want.  That’s precisely what we work on at Google. My hope is to provide instant access to any information anybody ever wants in the future.
