Abstract Diversified Radios and the Future Prospects Naoko OTANI Makoto YAMASHITA Since radio broadcasting started in, it has had a social effect on people accepting changes with the times and the advent of other media. Especially, in the days after the Second World War, commercial radio broadcasting stations were opened one after another, and radio was much utilized as media providing people with amusement such as music, dramas, and sports in addition to distributing news. Radio then functioned as local media with the start of local broadcasting in prefecture-based areas. After that, in, for the purpose of providing community-oriented information, a series of community-based broadcasting stations were opened in some parts of city/ ward/ town/ village-based areas, making radio closer to one than prefecture-based local broadcasting stations. In the s, as the Internet spread and media were digitized, the Internet radio distributing radio programs arrived, and it became possible for people to listen to the radio not through radio waves but through PCs, mobile phones, and PDAs. Moreover, while current analog radio broadcasting is going on, multimedia broadcasting for mobile devices which distributes screen images and data as well as sounds and music will be available in the near future as a policy of digital terrestrial radio broadcasting. This paper discusses a possibility that these diversified radios could have much effect on people s media uses and also change social functions of radios. 97
