Radio in Jonathia

Radio broadcasting in Jonathia has been used since the early 1920s to distribute news and entertainment to a national audience. By 1931, a majority of Jonathian households owned at least one radio receiver. It was the first electronic "mass medium" technology, and its introduction, along with the subsequent development of sound films, ended the print monopoly of mass media.
== Call letters ==
All radio stations are assigned unique identifying call letters by the Department of Media and Entertainment. Every station is assigned a code that starts with the acronym of their province, followed by either two or three randomized letters.
While some stations, especially on the AM band, still use their call signs as the main way of identifying themselves to the general public, a majority now prefer to emphasize easy-to-remember identifying slogans or brand names. Stations frequently choose call signs that relate to their slogan or brand; the LBC, for example, has used the call sign LLLB since 1946.
National and international stations rarely use their callsigns either on air or in branding and advertising; while they exist, they are more or less limited to government use.
