A code was needed to transmit natural language using only these pulses, and the silence between them. Thus, a speaker or a musician could easily fill time until the next segment appeared. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Broadcasts can be classified as "recorded" or "live". Westinghouse added other stations in different cities over the next two years, and General Electric and the newly formed Radio Corporation of America (RCA) soon entered the radio business as well.
