Two major program-oriented publications were Glenn Hauser’s periodic Review of International Broadcasting and Larry Magne’s annual Radio Database International. RIB was inaugurated in 1977 and focused on opinion and discussion about programming during its 20 year life. Varied in content, and somewhat idiosyncratic, it had many contributors and contained a wealth of information not usually available in club bulletins. Radio Database International, inaugurated in 1984 and soon renamed Passport to World Band Radio, has been a major attempt to serve, and help expand, a consumer audience for shortwave.
2. The Shortwave Audience 21 target of the research. Today, in addition to shortwave, international broadcasting encompasses rebroadcasting over local AM and FM stations, satellite radio, internet broadcasting, cable radio, and television. Stations are interested in knowing about all the vehicles by which they reach their audiences. 9 Listeners may not recall by what means they heard a particular station, and in some parts of the world, especially underdeveloped countries, listeners may not even know the difference between, for example, shortwave and medium wave, and may be unfamiliar with the particular bands to which they are tuned.
The Shortwave Audience 23 Radio RSA in South Africa received almost 24,000 letters. By 1988 the number had grown to 120,000. The ﬁgure for the BBC External Services was 300,000 in 1974,¡8 340,000 in 1982. ¡9 Deutsche Welle received the same number in 1982. In 1983, HCJB received 75,000 letters, and the following year Radio France International received 127,000 letters from 174 countries. Radio Japan received 80,652 letters in 1986–87, of which a modest 4,019 were from the United States. The year 1986 brought Deutsche Welle 390,775 letters, including 15,000 from North America.
