In 1920 the first radio station in the country, KDKA in Pittsburgh, began broadcasting. One of the station’s engineers was a member of a local Episcopal church. Since the station needed programming it agreed to air the church’s Sunday services. The response from listeners was so positive that fledgling stations around the country made church services an integral part of their weekly programming.
Impact: From these humble beginnings, religious broadcasting became a multi-billion dollar industry by the end of the century.
