You will see all the formats you mentioned minus music. You will see religious or possibly ethnic. Used to clear certain programming like Rush or the new African American news network.

The AM band will eventually fall wayside. As the older demos pass on, there will be less listener ship. Technology has changed listener consumption, offered on demand and high fidelity, which AM can't offer.

Sadly, the US govt pissed a lot of time away and helped kill the band. If they had adopted AM Stereo earlier and stuck to one type of encoding along with DAC used in Europe, it would be a different ballgame.
