Ran across the item below on the launch of FM radio, and now I understand the etymology of why FM stations are where one finds classical music stations, though we all know FM broadcasts are clearer and have less crackle than AM stations, where we typically find sports and news. When I was a student at the University of Chicago, my grand parents bought me my first new car, a red VW Beatle. It was the early 60s and most people had AM car radios, but I pleaded for them to  allow me to have an FM/AM model, because I wanted to listen to jazz and classical music while commuting to and from class. That  upgrade also upgraded the quality of my life. Thanks, FM, and grand parents, too.

“It was on this day in 1935 that listeners first heard FM radio, when the American inventor Edwin Howard Armstrong gave a demonstration in Alpine, New Jersey. Armstrong demonstrated the clarity of FM compared to AM radio by playing classical music and the sound of water being poured.”
