Radio
Radio-wave technology is one of the most important technologies used by man. It has forever changed the United States and the world, and will continue to do so in the future. Radio has been a communications medium, a recreational device, and many other things to us. When British physicist James Clerk Maxwell published his theory of electromagnetic waves in 1873, he probably never could have envisioned the sorts of things that would come of such a principle (White). His theory mainly had to do with light waves, but fifteen years later, a German physicist named Heinrich Hertz was able to electrically generate Maxwell's rays in his lab. The discovery of these amazing properties, the later invention of a working wireless radio, and the resulting technology have been instrumental to America's move into the Information Age (White). The invention of radio is commonly credited to Guglielmo Marconi, who, starting in 1895, developed the first wireless radio transmitter and receiver. Working at home with no support from his father, but plenty from his mother, Marconi improved upon the experiments and equipment of Hertz and others working on radio transmission. He created a better radio wave detector or cohere and connected it to an ea
Around the 1970s microcircuits replaced printed circuits. Plastics were put to use in the casing of the components, instead of a heavy wooden covering. Amplifiers of the radio currents enabled modern style speakers to be used to translate electrical impulses and currents into sound. The development of radio throughout the 20th century has led to many new and wonderful uses and products. These include: television, radar, the Global Positioning System of satellites, remote-control, cellular mobile telephones, cordless telephones, and commercial and private satellite communications (Fenton). The cost of radio devices has also changed American society. Modern radio receivers for purely audio broadcasts are pretty cheap, some types obtainable from dollar stores (for $1 obviously). Televisions, wireless and cellular phones, and other advanced radio systems are more expensive, yet not impossibly expensive for a working middle-class citizen. This availability to the majority of the population has increased use of radio devices, raising awareness of local, national, and global news. Unfortunately, this increased use also created a new part of society, which is lazy and addicted to television in many cases (Fenton).

Radio has helped the US economy and helped all citizens become more informed about world issues and news. It has made life much easier for everyone and aided us all in obtain better knowledge about our surroundings. It has advanced our science and knowledge past our own planet, and assisted in furthering our technology (Fenton). On the other hand, we all could become detached from the world with the ease given us by the technology we have created. Advances such as television, while having the ability to help us by making us more aware, entertaining, and educating us, also have proved (with overuse) to become a bad habit and capable of causing atrophy of the imagination. Radio has shown us, as many inventions do, what great moderation and responsibility we must use with any new discovery.
