Call Us In modern society, radios are common technology in the car and in the home. In fact, in today's world one would be hard pressed to find anyone who has not heard of, seen, or used a radio during his or her life, regardless of how old or young they may be. This was not always the case, however. Before the 19th century, wireless radio communication in everyday life was a thing of fantasy. Even after the development of the radio in the late s, it took many years before radios went mainstream and became a household fixture. The history of the radio is a fascinating one that changed how the world connected and communicated from distances both far and near.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio , many people contributed theory and inventions in what became radio. The idea of wireless communication predates the discovery of "radio" with experiments in " wireless telegraphy " via inductive and capacitive induction and transmission through the ground, water, and even train tracks from the s on. James Clerk Maxwell showed in theoretical and mathematical form in that electromagnetic waves could propagate through free space. In Heinrich Rudolf Hertz was able to conclusively prove transmitted airborne electromagnetic waves in an experiment confirming Maxwell's theory of electromagnetism. After the discovery of these "Hertzian waves" it would take almost 20 years for the term "radio" to be universally adopted for this type of electromagnetic radiation  many scientists and inventors experimented with wireless transmission, some trying to develop a system of communication, some intentionally using these new Hertzian waves, some not. Maxwell's theory showing that light and Hertzian electromagnetic waves were the same phenomenon at different wavelengths led "Maxwellian" scientists such as John Perry, Frederick Thomas Trouton and Alexander Trotter to assume they would be analogous to optical signaling   and the Serbian American engineer Nikola Tesla to consider them relatively useless for communication since "light" could not transmit further than line of sight.
Radio , sound communication by radio wave s, usually through the transmission of music , news, and other types of programs from single broadcast stations to multitudes of individual listeners equipped with radio receivers. From its birth early in the 20th century, broadcast radio astonished and delighted the public by providing news and entertainment with an immediacy never before thought possible. Broadcast radio remained the most widely available electronic mass medium in the world, though its importance in modern life did not match that of television, and in the early 21st century it faced yet more competitive pressure from digital satellite - and Internet -based audio services. More readily and in a more widespread fashion than any other medium, radio can soothe listeners with comforting dialogue or background music, or it can jar them back into reality with polemics and breaking news. Radio also can employ a boundless plethora of sound and music effects to entertain and enthrall listeners. The history of radio programming and broadcasting around the world is explored in this article. The first voice and music signals heard over radio waves were transmitted in December from Brant Rock, Massachusetts just south of Boston , when Canadian experimenter Reginald Fessenden produced about an hour of talk and music for technical observers and any radio amateurs who might be listening.
In , much of the world was in the grip of the Great Depression. Unemployment was an epidemic, and many businesses struggled desperately to survive. One notable exception to these economic troubles, however, was the radio industry. Broadcasters in the US were making upwards of two billion dollars a year, and they owed much of their success to the innovations of a brilliant man named Edwin Armstrong. Twenty years earlier he had significantly improved the sensitivity and quality of radio receivers with his invention of the regenerative circuit in his junior year of college, and he went on to further improve them with his Super Regenerative circuit and Super Heterodyne receiver. These laid the foundation for the success of radio broadcastingó in fact, almost any radio you buy today will still incorporate these innovations. But in , Armstrong brought about an even more revolutionary change in the broadcasting business: FM radio.
Radio: History and Production
Radio in the United States
The United States Radio Industry began in when American engineer, Edwin Armstrong, invented a special circuit that made long-range radio transmission of voice and music practical. Crystal radios required earphones so only one person could listen at a time. Vacuum tube radios could drive loudspeakers, which allowed the entire family to listen to the radio together. One of the important events during his presidency was the 's Radio. What was America's first Radio Station? What was the cost of a 's Radio?
At its most basic level, radio Communication through the use of radio waves. This includes radio used for person-to-person communication as well as radio used for mass communication. Both of these functions are still practiced today. Although most people associate the term radio with radio stations that broadcast to the general public, radio wave technology is used in everything from television to cell phones, making it a primary conduit for person-to-person communication. Guglielmo Marconi is often credited as the inventor of radio.
All electrically-based industries trace their ancestry back to at least B. In , William Gilbert, an Englishman, distinguished between magnetism, such as that displayed by a lodestone, and what we now call the static electricity produced by rubbing amber. Assisted by Henry, an American artist, Samuel F. Morse, developed a telegraph system utilizing a key to open and close an electric circuit to transmit an intermittent signal Morse Code through a wire. The possibility of transmitting messages through the air, water, or ground via low frequency magnetic waves was discovered soon after Morse invented the telegraph. Stubblefield, a Kentucky farmer, in
Radio broadcasting in the United States has been used since the early s to distribute news and entertainment to a national audience. It was the first electronic " mass medium " technology, and its introduction, along with the subsequent development of sound movies , ended the print monopoly of mass media. During radio's "Golden Age" it had a major cultural and financial impact on the country. However, the rise of television broadcasting in the s relegated radio to a secondary status, as much of its programming and audience shifted to the new "sight joined with sound" service. Originally the term "radio" only included transmissions freely received over-the-air, such as the AM and FM bands, now commonly called "terrestrial radio". However, the term has evolved to more broadly refer to streaming audio services in general, including subscription satellite, and cable and Internet radio. Under its oversight a variety of broadcasting services have been developed, including:.
Most radio historians asert that radio broadcasting began in with the historic broadcast of KDKA. Few people actually heard the voices and music which were produced because of the dearth of radio receivers at that time. The public, however, was overcome by a radio craze after the initial broadcast. Radio became a product of the mass market. Manufacturers were overwhelmed by the demand for receivers, as customers stood in line to complete order forms for radios after dealers had sold out. Between and , 60 percent of American families purchased radios. Families gathered around their radios for night-time entertainment.
