Radio Commercialization

Radio has been one of the best means of communication since its invention. It has been also developed with the passage of time. One of the developments of radio can be seen in the form of radio airplay. Now, radio airplay is becoming very popular amongst the people. Here in this article we will mainly be discussing about radio commercialization. Marconi has been credited for the invention of radio, in 1897; he established a radio station on the Isle of Wight, England. He opened his “wireless” factory in Hall Street, Chelmsford, England and employed around 50 people.

Commercialization of radio started with the invention of vacuum tube detector by Westinghouse engineers. For broadcasting the 1st program on radio program from Ocean Bluff-Brant Rock, Massachusetts; Reginald Fessenden utilized a synchronous rotary-spark transmitter. According to the sources, the 1st news program on radio was also broadcast on 1920, August 31 by station 8MK in Detroit, Michigan, which now seen as all news format station WWJ owned by CBS network.

In the early twentieth century, radio was further developed and commercialized. Its first advancement or radio commercialization in early 20th century can be seen when commercial AM radio stations were being utilized in aircraft for navigation. This however, goes on till early 1960s when VOR systems became widespread. In the early 1930s, amateur radio operators come up with single sideband as well as frequency modulation. However, by the end of the decades they also established commercial modes. The Regency company also introduced a pocket transistor radio which is powered by a "standard 22.5 V Battery" in 1954 and this led the way in commercializing radio in 1960s.

After the introduction of pocket transistor radio by the Regency Company, the Sony Company also comes up with its first transistorized radio in 1960. It was a small and can be powered by a small battery. The radio also had no vacuum tubes to be burn was so it was quite durable. And for over the next 20 years transistors replaced tubes almost completely except for very high power transmitter uses. In the 1970s, LORAN became the premier radio navigation system. However, in early 1990s, amateur radio experimenters started using personal computers with audio cards to process radio signals. Moreover the Digital transmissions started to be applied to broadcasting in the late 1990s. This is how radio commercialization takes places with the development of technology.
