(The invention of the transistor and development of semiconductors during the 1950s meant a radical change in technology in the radio industry. Vacuum tubes could be eliminated, and when mass production of transistors began, radios could be made both smaller and less expensive. The first transistor radio in the Radiola series was launched in 1958.)
