Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (radio). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM, FM radio stations transmit in FM, which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB, HD radio, DRM. Television broadcasting is a separate service which also uses radio frequencies to broadcast television (video) signals.

The pioneers of radio in Poland were army officers. These were Poles who served in the German, Austrian and Russian armies in the World War I. In the fall of 1918, shortly after the war, these experts started organizing Polish radio. On November 4, 1918, in Kraków, a field station, previously used by the Austrian army, sent the first Polish radio signals. Soon, more field stations – this time German — were captured by the Poles in Warsaw and Poznań. Obviously, at first radio was used for military purposes only.
