…On this day in 1935 Edwin Armstrong presented his paper "A Method of Reducing Disturbances in Radio Signaling by a System of Frequency Modulation" to the New York section of the Institute of Radio Engineers. This became the basis for FM radio which had better music capability than AM radio. Back when I was young FM radio was largely used for nothing but classical music because it was thought that they should make use of the better signal than pop music. It didn't take long for that to go away though.
