The EOTO presentation on the invention of the radio was interesting to me and taught me lots of information that I did not know previously. One of these facts that was unknown to me is that the first radio broadcast was transmitted in 1885 by Italian inventor Guglielmo Marconi.
Radio broadcasting began commercially around 1900, and were heavily used initially by the U.S. Navy. The Navy equipped their ships with radio transmitters in order to communicate to each other. Around World War II in the late 1930s / early 1940s, the use of the radio expanded by allowing music to play on different stations. Another use of the radio around this time was the invention of The Fireside Chats by President Franklin D. Roosevelt. During the Great Depression, FDR used the radio and his "fireside chats" to communicate with Americans and make them feel a special with him.
A lasting positive impact of the radio is the spread of information and ideas throughout the nation and the world. Another pro that can still be seen today is the enhancement of the music industry as many radio stations play music on the air. The large audience that radio broadcasts reach and have reached over the years has allowed the radio to become on of the most important inventions in the history of human communication and information sharing. A negative impact that the radio has had on the world is radicalized political views on broadcasts that have caused a greater divide, especially in America.
