An unbroadcast program is recommended to a user. A server is supplied with degree of preference data as indices of the taste of users for programs from user terminals, and calculates, based on this, correlations of the preference tendencies for the programs of other users using a service. The user terminal displays an electronic program table transmitted from the server, and when a reservation to view or record is input from the user, reservation information is transmitted to the server. The server calculates predicted values of degrees of preference of the respective users for programs to be broadcast in the future on the basis of the correlations of the degrees of preference and the reservation information, and transmits them to the respective user terminals. The user terminal refers to the degree of preference predicted values of the broadcast scheduled programs, and prepares a list of programs to be recommended to the user.
