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. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.

https://en.wikipedia.org/wiki/RadioSee more on en.wikipedia.orgRadio waves are radiated by electric charges undergoing acceleration. They are generated artificially by time varying electric currents, consisting of electrons flowing back and forth in a metal conductor called an antenna, thus accelerating. In transmission, a transmitter generates an alternating current of radio frequency w…- https://en.wikipedia.org/wiki/Timeline_of_radio
