I'd like to put a theory to you: what if AM radio were discontinued in the USA and Canada? In many countries around the world, AM or Medium Wave bands have become bereft of radio stations as they move to FM or DAB frequencies. Let us suppose the FCC and the CRTC decided to do away with it. Where do you think the stations would move? Would they move to the already crowded FM band? Would they go all digital or online? Or would they close down? Let's talk about this idea. Your comments are welcome.
