This radio receiver can receive medium and long wave broadcasts, and is cased in a wooden cabinet. This is a typical two-waveband table-top wireles set from the 1930s. Broadcasting developed rapidly after the first succesful transmision of the human voice in 1906, and in 1922 the British Broadcasting Corporation was set up. This concept of public-service broadcasting funded by licence revenue influenced broadcasting in many other countries. By 1943 the BBC was broadcasting around the world in 47 languages.
