How was a radio used when originally invented?
When originally invented, the primary use of radio was for communication. The first experiments in radio communication involved the transmission and reception of Morse code signals. In the late 1890s, Guglielmo Marconi demonstrated the practical use of radio for long-distance communication, leading to the development of radiotelegraphy. This allowed for communication between ships and land, as well as between distant points on land, revolutionizing communication technologies at the time.
