When was the radio mass produced?

Answer 1

In 1920-1921, if you wanted a radio, you generally had to make your own, and since most of the early radio broadcasters came from amateur (ham) radio, this was not difficult. There were a number of ham radio magazines that offered instructions on building a radio receiver. But when the radio craze exploded in mid-1922, and hundreds of new stations went on the air, listeners no longer came exclusively from ham radio, nor did the broadcasters. Suddenly, not everyone knew how to build a set, but demand for radios was increasing dramatically. By 1923, you could find radio sets from companies like RCA (Radio Corporation of America) and Westinghouse for sale in most department stores, and these manufacturers were joined by a number of others. By 1925-26, the major manufacturers of radio sets had shifted their focus from advertising technological features to advertising what you would be able to hear on the air, and how beautiful the new set would look in your home.
