Yes, it looks like "managed, intentional devaluation of spectrum with unique, valuable characteristics".
Canada has left AMs, such as CBK in Watrous (Saskatchewan plains) where the AM would render a good service. They have allowed abandoned AM licenses in larger metros to sign on with new owners who offer specialized services to groups that exist in places like Toronto and Vancouver.
Mexico determined that AMs were approaching a point where they would not be economically viable, and has made provisions for as many as 75% of all AMs to move to FM, thus not depriving the audience of diversity in programming due to the reduction of "real" radio service (they saw that a band nobody listened to did not provide service or diversity). Throughout Latin America, there has been great attrition in the number of AMs: El Salvador has half the stations of 25 years ago, and half are now evangelical / Christian in a nation where 90% of the population is Catholic. Chile has seen a formerly leading 100 kw AM in Santiago, a market of 5 million, sign of due to losses and "no prospects" even in a boom economy. Quito, with 50 FMs, is losing almost all its AMs.
When either market realities that kill AM listening or the availability of enough FM channels for AMs to move, nobody will want to be on AM.
It is important to someone, somewhere, that information comes to us not directly from a "local" source, wherever that may be but through proper channels and national networks, so that information can have the proper spin.
I don't see the relationship between control and AM (of course, with so many distribution methods, I don't see an issue there anyway). A market with a news talk station on FM is no different than one with the format on AM, except that in most markets the full signal FM covers more than any of the local AMs (Madison, WI, being a great example and one that you raised).
Destroying AM will help ensure that no one will be motivated to drive from Chicago to "help" with something goverment would rather see squashed.
Huh? What Madison station can be heard by the average Jane or Joe in Chicago? None. Even thinking that anyone who does not need a walker might find WTMJ and actually listen is totally disingenuous.
When you look at AM listening, it is predominantly over 55, and under age 35 nearly non-existent except for the cases where play by play sports are only on AM. In some markets, AM listening is now way below 10% of the total, and in a number it is around 5%. Only a few markets have even two full coverage AMs, and many have none!
MW has been hated by numerous tyrannical governments precisely because it is too hard to control geographically.
It's historically been Short Wave that has crossed borders... not MW. Except for a few cases, like Berlin, where a city was divided by the Iron Curtain, AM does not do a good job of covering populations of one country from the territory of another. USIS has used an AM in the Keys to "cover" Cuba, but there is little evidence that the signal gets widespread reception. VOA had a megawatt in the Philippines on 1140, aimed at China, with little evidence it was being heard. Save a few cases, MW is not useful for "preserving freedom" as it is easily blocked.
So far, we have the general public... two generations of it... rejecting AM and no evidence that any programming works "better" on AM.
