PROBLEM TO BE SOLVED: To enable even a person with no means to send digital contents. SOLUTION: An administrator 1 invites plural digital content senders 2 and 2 and plural assenting enterprises or groups 3 and 3 and mediates between those digital content senders 2 and 2 and assenting enterprises or groups 3 and 3 to allow them to make a contract that at least the loss of the cost needed to send the digital contents is regarded a benefit and at least the advertisement conducted when the digital contents are sent is regarded as return service. At sites for digital content transmission which are opened on the Internet, the digital content senders send the digital contents at low cost or free. |
