Radio is the wireless transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light.
Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. It does not require a medium of transport. Information is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude or their frequency. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.
The word 'radio' is used to describe this phenomenon, and television, radio, and cell phone transmissions are all classed as radio frequency emissions.
Before the advent of television, commercial radio broadcasts included not only news and music, but dramas, comedies, variety shows, and many other forms of entertainment. Radio was unique among dramatic presentation in that it used only sound.
Radio content in the Golden Age of Radio had its origins in audio theatre. Audio theatre began in the 1880s and 1890s with audio recordings of musical acts and other vaudeville. These were sent to people by means of telephone and, later, through phonograph cylinders and discs. Visual elements, such as effects and sight gags, were adapted to have sound equivalents. In additions, visual objects and scenery were converted to have audio descriptions.
