A non-limiting example game system includes a game apparatus which is stored with various kinds of application programs. When an application program for a specific service such as a television program guide (program guide program) is started, prior to an acquisition of a content (webpage), an authentication of the game apparatus is performed, and a white list which records a domain name accessible by the game apparatus (the program guide program) is acquired from a managing server which is controlled by a provider of the television program guide. In the program guide program, it is determined whether or not a domain name described in URL of the webpage appears in the white list when a request to send the webpage is to be sent. If not appeared in the white list, the program guide program is suspended, and a web browser is activated to send the request to send the webpage.
