Not in the USA. We still have 50,000 watt clear channel stations. On a clear winter night, local lore has it that WJR-760AM Detroit could be heard in Mexico. Crystal radios still work...well, not fine, but as good as they ever did. AM frequencies are low enough they skip off the ionosphere.

I always think about this when I see another story about AM's demise.

On shortwave, we even have 250,000 W transmitters just blasting RF everywhere.
We call them flame throwers for a reason.
