Introduction
Although Guglielmo Marconi is believed to be the inventor of the radio, many other physicists made a significant contribution to its improvement. Reginald Fessenden became famous for transmitting the human voice without wires for the first time in history. In 1906 he broadcasted a Christmas concert, including his voice and violin play with the help of 400-foot towers to the ships of the United Fruit Company, which were equipped with Marconi’s radios. He imprinted a voice on the radio wave with the help of an electric generator. Moreover, Canadian pioneer patented and helped to invent many components currently used in radiotelephony such as the “beeper,” Alexanderson alternator, and the concept of the broadcast.
Main body
Before 1922 communication companies could earn money only through two-way charges like telephone, telegraph, and sale of radio equipment. In 1922 the first-ever commercial promoting the sale of apartments was broadcasted by the New York station WEAF. It was the first paid radio advertisement, which cost Queensboro Corporation 50 dollars for 50 minutes. This broadcast is essential because it started the commercial era of radio, and people understood how to make money from the miracle technology. Currently, it is difficult to imagine popular radio channels’ broadcasts without commercial breaks.
FM (frequency modulation) technology was developed and introduced by Edwin Armstrong in 1933. FM, together with stereo, significantly increased the quality of audio. The emergence of FM technology changed the audio market, as it had more capacity for sound reproducing. This technology became popular only in the mid-1950s with the introduction of stereo record players on the market. FM was appropriate to receive and transmit the stereo signals with very low and high frequencies, which made it more widespread. This event ignited the competition in the radio industry, which was suppressed by television earlier.
Conclusion
In 1954 the song “That’s All Right” was firstly played on the air by Dewey Phillips at WHBQ. It was the first time when radio listeners heard the music of Elvis Presley, who is still considered as a king of rock and roll. By mid-1955, the singer already had about ten singles, which young people enthusiastically enjoyed. The new style of music had the effect of an exploding bomb. In general, Presley yielded a strong influence on pop culture by spreading rock and roll music and influencing youth culture, who were inspired by him to be different.
