In the beginning


The radio tube Triode was invented in 1907. It made it possible to build radio transmitters and receivers that not only sent out Morse code but also speech, song and music, that could be heard with a radio receiver. Around 1920, technological developments made it possible to start regular broadcasts to the public. In the early days these transmitters were operated by private initiative and were usually financed by advertisements. K.G. Eliasson built this transmitter and broadcast programmes in the Gothenburg area during the years 1920-24.

The Swedish Radio Service, which later became Swedish Radio, started operating on January 1, 1925. From this date onwards it was forbidden to use advertising incomes to finance broadcasts in Sweden. It was 1993 before they were allowed again.
