The discovery that electromagnetic waves are capable of transmitting information sparked the invention of radio. The technology scaled like the old inventions in the telegraph as well as the telephone. According to some researchers, the amplitude modulation technique originated in the experimental and theoretical work of Leblanc, in 1886, Mayer (1875) and Rayleigh (1894).
