Radio started off as a series of dots and dashes, which were used to relay messages. It later turned into a complete audio phenomena through wires, employing electromagnetic radiation. Signals were sent through what was known as, a “wireless telegraph." After a while, certain messages weren't able to be relayed, based on the fact, that they were located to far from a strong connection. This forced the need for a new type of communication system. Radio's purpose was to send signals across a distance, using codes that the receiver could interpret.
The Development
After the development of the telegraph, Alexander Graham Bell took it upon himself, to form an “electric speech machine,” in 1876. This creation was a system where information was sent through sound, allowing people to communicate over great distances. In the 1880’s, when Heinrich Hertz was demonstrating his development, based on the theory, that electromagnetic waves behave in the same way as light, and that light itself is electromagnetic in nature, employing “electromagnetic radiation” thus creating sparks, he proved that wireless telegraphing was possible. His theory unfortunately failed. Hertz received help from an Italian inventor, Guglielmo Marconi. Marconi's creation of a wireless transmission system, allowed sound waves to travel over great distances, without using wires such as the type of wires that were used with Morse Code. The Morse Code consisted of three "dit" sounds. That was the beginning of the theory, that sound without wires couldn't exist. Soon after that development, the creators went through a process of trying to figure out the proper name to call this new technology.
The Development of Commercial Radio (From the book Making it in Radio)
Dan Blume stated, "Radio is an industry that reaches out to about 95 percent of Americans every week and around 75 percent everyday." [2] Blume did research and on average a household contains six radios, with the ones in the cars. Also, about 60 percent of the population is woken daily by the radios in their alarm clocks. [2] Blume stated, "Radio reaches more people daily than television, newspapers, or magazines." Radio affects each and every listener. It could be a reflection in their attitude and/ or their behavior. Blume said that, "American commercial radio is a system of stations and networks that derive revenue from advertisers who wish to reach audiences with messages about
