Abstract: A method and system for single-action personalized recommendation and display of content via the Internet. The recommendation is given by a server system and received by a client system. The content itself has been previously recommended to the server system by the users of the client system. Client system recommendations to the server system are also invoked with a single-action. Recommended content is referred to by a URL. Users can rate content to the server system using a single-action. The server system performs recommendation calculations using user-specific information such as user preferences, demographic data, content rating history, and content-specific information. The content rating history of other users may also influence these calculations. Client systems display recommended content directly to the user in response to only a single-action.
