The TV program table data in the area where a viewer resides are received through the Internet or a broadcasting medium by using the TV set with an internet connection function at the viewer. While the viewer is watching a TV program, the audience data including viewed channel information and viewed time information are automatically obtained. The obtained audience data are compared with the TV program table data to identify the watched program. The program ID of the identified program and the viewed time information are transferred to a data collecting center through the Internet together with the viewer ID data. By utilizing the Internet for the distribution of the TV program table data to the viewers and for the collection of the audience data, the nationwide TV audience data can be easily collected and used to make statistics. Since viewed channel and viewed time information are correlated with programs on the viewer's side, the load of processing the data on the center side can be relieved.
