The term Old Time Radio refers to the relatively brief period from 1926, when the National Broadcasting Company first began network broadcasting, until approximately 1960, when television became the dominant communication medium in the United States. During this time, radio was as popular and ubiquitous as television is today. It was amazingly varied in the types of programming it offered; many characters and programs were so popular that virtually everyone was familiar with them. Even today, recorded versions of these programs are still extremely popular and widely available, both from commercial outlets and from hobbyists. Behind the production of these programs was a complex technological and financial infrastructure that had to be developed virtually from scratch in a world unaccustomed to the rapid communication and technological marvels that we take for granted today.
