Learning Objectives. Identify the major technological changes in radio as a medium since its inception. Explain the defining characteristics of radio’s Golden Age. Describe the effects of networks and conglomerates on radio programming and culture. At its most basic level, radio is communication through the use of radio waves.
The radio broadcasting of music and talk intended to reach a dispersed audience started experimentally around 1905–1906, and commercially around 1920 to 1923. VHF (very high frequency) stations started 30 to 35 years later.
