Abstract: In a first information processing apparatus, a plurality of users can be registered. When an application is executed, any of the registered users is selected as an application executing user. Execution state data in which application information indicating the application being executed is associated with the selected user is transmitted to a server. In the server, the execution state data is aggregated to generate aggregate data. In this case, the aggregation is performed such that an execution state of the application is recognizable for each application executing user. The aggregate data is transmitted in response to a request from a second information processing apparatus. The second information processing apparatus displays the execution state of the application for each application executing user on the basis of the received aggregate data.
