New technology has changed the image of the radio since the 1920s till today. The radio started off as a simple “wireless telegraph” that was used to send out Morse code to and from ships. Then, when Lee de Forest invented the vacuum tube, sound, voice, and music entered the world of the radio. The radio began to drift from a military and government use to a public use. Now radio stations played anything from the news to music to shows, such as soap operas. When television was invented, radio stations were hurt greatly because no one listened to the radio anymore; instead, they tuned into their favorite shows on the TV. Finally, when FM radio and DJ’s appeared, the radio became more widely used again, for news, talk, and music.
Satellite radio is affecting the evolution of the radio in the U.S. today. Now, anyone in the county can listen to one source of radio anywhere they. With satellite radio increasing in popularity, soon, local radio stations and DJ’s will become obsolete. Most people prefer their local stations because they follow a local DJ and listen to their set playlist of music; however the downfall of local stations is that their range only extends so far and the quality is not always the best. If satellite radio’s popularity continues to grow, FM radio will become a lot smaller and many people in the radio business will lose their jobs. In conclusion, technological changes have impacted the evolution of the radio more than any other factor because they have changed the radio from military use to a form public entertainment, given people a chance to stay connected with their community, and now, with satellite radio, allows people to listen to their favorite music where ever they are.
