The distribution control system includes a browser management unit configured to start up a browser appropriate for the communication terminals; a browser configured to generate the image and/or sound data by rendering content data; and a transmitter configured to transmit the image and/or sound data to the communication terminals. The browser management unit is configured to start up the browser for open use when outputting the image and/or sound data permitted to be open to the other communication terminals. The browser management unit is configured to start up the browser for personal use when outputting the image and/or sound data not permitted to be open to the other communication terminals.
