A system for automatically measuring the size of a radio or television audience at any particular time is provided. In the system, a remote computer may identify the broadcast stations to which listening devices, such as radios or televisions, are tuned. To identify the broadcast stations, the remote computer commands the listening device instructing/commanding the listening device to poll its radio receiver tuner to determine the frequency it is tuned to. This information is then transmitted from the listening device to the remote computer where it may be used to determine what broadcast station the listening device is tuned to. This data is then stored and accumulated, so that over time the listening habits of the user may be identified. The collected data may be used by broadcast stations to determine the cost of advertisements. Additionally, the system provides for the monetization of advertising by charging advertisers for downloads. |
