The current state of viewing-related data is that some receiver manufacturers have already collected it and advertising and research companies are using it in a variety of ways. On the other hand, broadcasters, including stations in Tokyo, are in the process of collecting data from various companies. The preparations for the use of the data are being made in a careful manner, while exchanging opinions on the legal system, technology, consumer groups, and many other areas in order to ensure safe and secure handling of viewing data. With the amendment of the Personal Information Protection Law this year, the guidelines for the broadcasting field and the guidelines of the Broadcast Security Center and other rules of use in the broadcasting field will be established. The people involved in the project will give an explanation and talk about the prospects for the collection and utilization of viewing data by broadcasters.
