Computer-readable storage medium, information processing apparatus, information processing system, and information processing method

An information processing system comprising:

• a storage section for storing content data;
• a processing system comprising a processor, the processing system being configured to control the information processing system to at least:
• execute the content data;
• transmit transmission data to one or more other information processing apparatuses, the transmission data including identification information for the executed content data;
• receive reception data from one or more other information processing apparatuses, the reception data from each respective other information processing apparatus including identification information for content data executed by the respective other information processing apparatus;
• and
• access purchase information for purchasing content data corresponding to at least one piece of identification information included in the reception data received from the one or more other information processing apparatuses.

An information processing apparatus comprising:

• a display screen;
• user controls;
• a communication module configured for short-distance wireless communication;
• and
• a processing system for executing content data and interfacing with the display screen, the user controls and the communication module, the processing system executing instructions for causing the information processing apparatus to at least:
• transmit transmission data to one or more other information processing apparatuses, the transmission data including identification information of the executed content data;
• receive reception data from one or more other information processing apparatuses, the reception data from each respective other information processing apparatus including identification information of content data executed by the respective other information processing apparatus;
• and
• access purchase information for purchasing the content data corresponding to at least one piece of identification information included in the reception data received from the one or more other information processing apparatuses.

An information processing method comprising,

• at an information processing apparatus comprising a display screen;
• user controls;
• a communication module configured for short-distance wireless communication;
• and a processing system,
• executing content data;
• transmitting transmission data to each of one or more other information processing apparatuses, the transmission data including identification information of the executed content data;
• receiving reception data from one or more other information processing apparatuses, the reception data from each respective other information processing apparatus including identification information corresponding to content data executed by the respective other information processing apparatus;
• and
• accessing purchase information for purchasing the content data corresponding to at least one piece of identification information included in the reception data received from the one or more other information processing apparatuses.

A portable information processing apparatus comprising:

• at least one display screen;
• user controls;
• a communication module configured for at least short-distance wireless communication;
• and
• a processing system interfacing with the display screen, the user controls and the communication module, the processing system executing application programs and being configured to cause the portable information processing apparatus to at least:
• transmit transmission data, via short-distance communication using the communication module, to one or more other portable information processing apparatuses, the transmission data including identification information at least for the most-recently executed application program;
• receive reception data, via short-distance communication using the communication module, from one or more other portable information processing apparatuses, the reception data from each respective other information processing terminal apparatus including identification information at least for the most-recently executed application program executed by the respective other portable information processing apparatus;
• and
• cumulatively store at least the identification information included in the reception data received from the one or more other portable information processing apparatuses.
