Radio History

The invention of radio required many discoveries in electronics and other fields to actually produce radio broadcast, first used as the wireless telegraph before evolving into a communication device capable of sending messages simultaneously to different locations. The Fleming valve was used before the Edison vacuum tube in radio transmissions. The Italian inventor Guglielmo Marconi is generally given credit with the invention of the radio. The Navy was the first to recognize the enormous potential of radio, and from the time it conducted tests on Marconi’s equipment it employed the use of radio broadcasts “The U.S. Navy began to equip its entire fleet with radio transmitters, and also set up an extensive chain of coastal stations. Radio was employed as an aid to civilian and military navigation. By 1908 the Navy was reporting that both warnings about sea obstructions, plus daily time signals, were being sent broadcast on regular schedules by its coastal stations” (White I; 1).
