Between Guglielmo Marconi and Nikola Tesla, there is still controversy on who invented the radio, even to this day. Many individuals across the world believe that Guglielmo Marconi, an Italian inventor and electrical engineer, sent and received the first radio signal in 1895. Quite frequently, individuals will credit him as the father of the radio. However, many sources proclaim that he used ideas from other inventors, primarily Nikola Tesla, to develop the first successful long-distance wireless telegraph which is the “transmission of electric telegraphy signals and information without wires, using wireless radio waves.” (source).
“In his Nobel Prize acceptance speech, radio pioneer Guglielmo Marconi — who was much more a tinkering engineer than a scientist—freely admitted he didn’t really understand how his invention worked.” (source)
This eventually led to the introduction of radio communication in the early 1900’s. At first, the radio was primarily used for military purposes with Morse codes. With the expansion of the radio after the First World War, broadcasting was officially developed in the 1920’s and quickly spread across the world in the following years.

When the television was invented, individuals used the radio mainly to listen to music.
