PROBLEM TO BE SOLVED: To make it possible to conduct an effective and accurate audience rating survey on Internet broadcast programs. SOLUTION: A network connection part 18 is connected to the Internet. A user ID database 12, a device ID database 13 and a distribution program schedule database 14 acquire a user ID specifying an audience of a network distribution program, a device ID that identifies a client terminal 50 that receives the network distribution program and a program ID that identifies the network distribution program to compile into database, respectively. The user ID and a feature parameter representing the feature of an audience are associated with and are registered with a demographic information registration summarizing part 15. A survey server 10, depending on every ID acquired from the client terminals 50 and the feature parameter retrieved from the demographic information registration summarizing part 15 according to the user ID, conducts the audience rating survey on the network distribution programs.
