Radio Timeline

  • Prediction of existence of radio waves

    James Clerk Maxewell predicted the existence of radio waves. His most notable achievement was to formulate the classical theory of electromagnetic radiation.
  • Radio Waves Could be Broadcasted into Space

    German physicist named Heinrich Rudolph Hertz demonstrated that rapid variations of electric current could be projected into space in the form of radio waves similar to those of light and heat.
  • Electric Waves Could be Transmitted Wirelessly

    Heinrich Rudolf Hertz was a German physicist who first conclusively proved the existence of electromagnetic waves theorized by James Clerk Maxwell's electromagnetic theory of light.
  • Radios placed on ships

    Before when ships would start sailing, they didn't have any way to communicate with land and if they got into some sort of trouble, they had no way to communicate with land.
  • Electromagnetic Energy Wirelessly Transmitted

  • First Speech and Music Transmission

    Reginald Aubrey Fessenden was a Canadian inventor who performed pioneering experiments in radio, including the use of continuous waves and the early—and possibly the first—radio transmissions of voice and music. Reginald Fessenden is the first to transmit a program of speech and music.
  • First Radio Transmission from an Airplane

    First Radio Transmission from an Airplane. Ground controls used visual aides to provide signals to pilots in the air. Next came the advent of portable radios small enough to be placed in planes, which for the first time offered pilots the ability to communicate back to the ground.
  • Radio Stations Closed

    All radio stations not needed by the government are closed as WWI begins. Civilian radio activities were suspended during the war, as the radio industry was shut down most private U.S. radio stations were ordered by the President to either shut down. The station reopened in January, 1915, with American Marconi.

  • Compressed audio MP3

    The Moving Picture Experts Group MPEG-1 Audio Layer III (MP3) compressed audio file format becomes an international standard, and eventually the most popular format for distributing digital audio over the Internet.
