Broadcasting- History and Evolution

Technical definition of broadcasting would be the proper channeling and distribution of audio and video signals. These signals help in the transmission of various programs to different audience. Usually, these audiences is scattered into wide array of sets. They could be huge crowd in a public place or they could be certain sub-section of people in groups.

Broadcasting could find its roots attached to the radio transmissions and wireless telegraphy because even those were transmission of signals in different formats though. From the secret usage of radio and radio signals in the world wars to the present day podcasting, broadcasting has traveled a long way out. It started with Charles Herrold trying different varieties of call signals to regulate radio and then graduated towards the stage of U.S. government recognizing the need for the radio signal transmission and the operators required for the purpose.

From radio the transition took over to the television media sector. The source of revenue started inclining towards television. This change occurred in 1950’s in various parts of the world. Even though the radio programs were being broadcasted after the invention of television but by 1960s many of the radio networks stopped producing programs. Even in the television broadcasting, there was transition from the monotonous black and white to the coloured stages.

Talking about history, the noticeable one is of television. There were baseball games being aired on the television, which was in the 1930’s. During those days it was only radio broadcasting that was more widespread but with the advent of television, many of the radio broadcasting companies had to sell off. It started off with the regular programs, progressed towards the broadcasting of various games and more. Proper commercial broadcasting did not begin until late 1940’s in United States. Even the colour broadcasting was approved in early 1950’s. Colour broadcasting was originally German patent in 1904. It was not until 1954, the colour broadcasts were approved.

From the conventional radio programs and channels there was an evolution from the AM radio to the FM radio stations. They changed entire outlook of the radio broadcasting. With the advent of the FM radio, there started the decline of the AM radio because of the reasons like poor signal coverage in the AM radio, lower cost of FM receivers and very narrow AM radio bandwidth. These changes took place during 1970-90.

A new millennium arrives and with it comes the digital radio phenomenon and direct broadcasting by the satellites in USA. From digital radio comes the digital broadcasting across the world. Even the television these days is the broadcasted directly by the satellites.

Broadcasting has evolved from the government funded stage to the public and that is called public service broadcasting. Public service broadcasting is the most prevalent in the broadcasting industry. The television, radio and several such media outlets which receive funding from the public come under the public service broadcasting sector. Public service broadcasting has changed the complete outlook of broadcasting.

Changes in the broadcasting equipment and technology take place very rapidly and the growth has always been on a progressive curve. A lot has happened to the date and even lot is still to come in the broadcasting technology.
