Abstract: A server includes a provider that provides, when a contents ID to identify contents is designated from a terminal, the contents associated with the contents ID to the terminal. The terminal includes a display that displays the contents obtained from the server on a screen. The provider puts predetermined suppress information in the contents when a busy level of the server is higher than a predetermined threshold. When a present date and time is within a display time period set to a popup message and the contents displayed on the screen do not contain the predetermined suppress information, the display displays, in the screen, the popup message so as to be laid over on the contents or displays the popup message instead of the contents, and when the displayed contents contain the predetermined suppress information, the display keeps displaying the contents in the screen.
