AM radio hasn't died yet. Heck, books haven't died yet. New media doesn't always kill old media.
Some lobbying very hard in various countries to introduce digital radio. When you look up the implementation details, it would be pretty bad idea to stop analog radio. Now some countries already mandate that radio in new cars and also try to mandate that all new sold radio in those countries are digital radio.
It's absurde as people listen less and less radio, and analog radio has a lot better coverage - even in bad signal quality you can actually hear something - something vital in emergency situations. Of course you cannot censor analog radio at all, pirate radio stations were common back then when things went wrong. And we already had a time when certin countries allowed just one type of radio device with just one radio channel.
