If you've never Googled, you probably aren't finding what you want online. Google operates the leading Internet search engine, offering targeted search results from billions of Web pages. Results are based on a proprietary algorithm -- Google's technology for ranking Web pages is called PageRank. The company generates nearly all of its revenue through ad sales. Advertisers can deliver relevant ads targeted to search queries or Web content. The Google Network is a network of third party customers that use Google's ad programs to deliver relevant ads to their own Web sites. Google subsidiaries include YouTube and DoubleClick. Founders Sergey Brin and Larry Page each have nearly 30% voting control of the firm. [Description from Hoover's]
