Google's vision is to organize the world's information and make it universally accessible and useful. Its mission focuses on innovation and the user experience. Google identifies its primary competitors as Microsoft and Yahoo, and aims to gain a major share of the worldwide web. It generates most of its revenue from search and advertising, such as AdWords and AdSense. To maintain dominance, Google needs to continuously innovate, find new revenue sources, focus on growing markets like BRIC nations, and potentially make more acquisitions in areas like social networking and video.
