Google's mission is to organize the world's information and make it universally accessible and useful. From its early days at Stanford University, the Google search engine has proven to return the most relevant results. Google has monetized search, being able to deliver advertisements that are relevant to the pages they are displayed on. Beyond search, Google offers many free services including Gmail, Google Maps, and YouTube. These services add to Google’s platform, and provide content for Google’s advertising. Google has not been successful in monetizing all of its products and services.
