As I said before on this thread, it depends on where you live. in Cincinnati, 2 of the top 5 rated stations are AM.in other markets. AM doesn't show up at all in the ratings.Aren't we getting away from the general topic.? There are a million reasons and causes of the electrical noise that has made AM radio unlistenable. No one is getting rid of their solar panels, microwave ovens, and aging insulators. The noise will remain. So AM stations won't. The lower powered stations are already hash 10 miles from the transmitter. The big guns are still there, but with half the range of 30 years ago. If they don't all switch to a digital format and all radios can't receive the signals, they will continue the progression of fading away. No legislation is or should be made to require HD radios. Even if it were so, how many would invest in one? The answer is simply to have better programming than anyone else on a band that people tune too, FM, satellite, or internet. If the message is worth hearing, the delivery system shouldn't matter. AM should not be encouraged to stay and burn a lot of electricity in 2024. There are too many boring stations offering too little quality. The big guys already know this and that's why so many group owned AM stations are rebroadcasting signals from a co-owned FM or infomercials simply to keep modulating. (please don't start a column to inform me that infomercials are a source of revenue to justify keeping AM alive) Just like the buggy whip, AM's time has come. Or is it AM's time has gone? Let's put something that might even generate water cooler talk on the air, whatever that air might be and then people might listen. Maybe advertisers might want to be a part of that and the money could be added to the budget of the FM station carrying it.
You can't just say no one listens to AM anymore, it depends on where you live.
