Abstract: After presentation target information for presenting information of a predetermined content to a user has been newly received from a predetermined server, a first notification that urges the user to check the newly-arrived presentation target information is displayed. Thereafter, while the presentation target information has not yet been checked, a second notification that urges the user to check the unchecked presentation target information is displayed periodically or according to a predetermined time schedule. The presentation target information is displayed when an operation to check the presentation target information is performed to the first notification or the second notification has been performed.
