Ten years ago this September, Sergey Brin and Larry Page were about to set up offices in a garage. Their Web site, Google.com, delivered results for 10,000 searches a day. By 1999, that figure had jumped to 3 million. Today, Google processes hundreds of millions of searches each and every day. If this is a staggering number, consider that behind each and every search query is a set of consumer data, and it is access to this data that puts Google into a league of its own.
