  3. Invention • During the 1860s, Scottish physicist, James Clerk Maxwell predicted the existence of radio waves. • in 1886, German physicist, Heinrich Rudolph Hertz demonstrated that rapid variations of electric current could be projected into space in the form of radio waves. • In 1866, Mahlon Loomis, an American dentist, successfully demonstrated "wireless telegraphy.

  4. Marconi • Guglielmo Marconi, an Italian inventor, proved the feasibility of radio communication. • He sent and received his first radio signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel. •  This was the first successful transatlantic radiotelegraph message in 1902.

  5. Nikola Tesla • In addition to Marconi, two of his contemporaries Nikola Tesla is now credited with being the first person to patent radio technology; the Supreme Court overturned Marconi's patent in 1943 in favor of Tesla.

  6. Harold & Edwin • On March 8, 1916, Harold Power with his radio company American Radio and Research Company (AMRAD), broadcast the first continuous broadcast in the world. • Inventor Edwin Howard Armstrong is credited with developing many of the features of radio as it is known today. Armstrong patented three important inventions that made today's radio possible.

  7. Fessenden • Canadian, Reginald A. Fessenden is best known for his invention of the modulation of radio waves and the fathometer. • Fessenden started his own company where he invented the modulation of radio waves, the "heterodyne principle”.

  8. Military Use and Patent Control • When the United States entered the first world war in 1917, all radio development was controlled by the U.S. Navy. • In 1919, after the government released its control of all patents, the Radio Corporation of America (RCA) was established with the purpose of distributing control of the radio patents that had been restricted during the war.
