The term old time radio encompasses radio recordings made usually between the mid 1920's through 1960. This "golden age of radio" included all genres of amazing recordings which were frequently performed live by top name performers. Old Time Radio (OTR) and the Golden Age of Radio refer to a period of radio programming in the United States lasting from the proliferation of radio broadcasting in the early 1920s until television's replacement of radio as the dominant home entertainment medium in the late 1950s. During this period, when radio was dominant and the airwaves were filled with a variety of radio formats and genres, people regularly tuned in to their favorite radio programs. In fact, according to a 1947 C. E. Hooper survey, 82 out of 100 Americans were found to be radio listeners.
