A broadcast receiver includes a controller that detects a reception log of a receiving unit and that records the reception log in a reception log memory. The reception log includes at least the reception channel, reception start time, and reception end time. Periodically an audience member connects the broadcast receiver to a general-purpose computer. The general-purpose computer transmits the reception log data recorded in the reception log memory with a receiver ID written in a ROM through a telephone line over a communication network, such as the Internet. A person who computes viewing/listening information obtains the reception log data and receiver ID from the communication network and computes viewing/listening information, such as a program rating. Instead of providing the broadcast receiver with the reception log memory and a computer interface, a removable storage unit with a computer interface can also be used.
