We don't really know for certain who invented or built the first radio. Some people say it was Guglielmo Marconi, while others say it was Nikolai Tesla. Radio receivers in those early days (1900-1912) were hand-made: you would order the parts from a store that sold electronic equipment, and follow the diagrams printed in electronics magazines. Early radio sets were operated by amateur hobbyists, who sometimes sent messages via Morse Code, and sometimes sent messages by voice.
We do have evidence that as early as 1905-1906, an inventor named Reginald Fessenden was able to send out voice and music, and at least one college station, operated in San José, California by Professor Charles "Doc" Herrold and his wife Sybil, played the hits and took requests as early as 1911-1912. But commercial radio did not begin until 1920, in cities like Detroit, Pittsburgh, Montréal, and Medford Hillside (MA); and it wasn't until about the mid-1920s when you could go to a department store and buy a professionally designed (and nice-looking) radio.
