The first radio broadcast in the world was made in England in 1922. Wireless preceded it but was used mainly for military purposes. By the early 1920s, crystal sets were the commonest receivers, used in the home by enthusiasts who spent long hours making and operating them. valve sets developed alongside them and by the 1930s, the radio was cased in wood or bakelite.
