Don't confuse what I am about to suggest with the often heard "live and local" mantra. That usually means the writer things we need to go back to a 1960s through 1980s dj play hit records and chatting us up. No!
However. I look around me at the people in their 60s, 70s and even 80s that have either conquered how to load content on their iPods or have found someone to do it for them.
The national talk, both political and sports, migrating to FM, one can make an argument there is nothing left to fill up the cauldrons of AM stations.
Content that is national in interest will gravitate toward the national (FM) talkers, or if it is of interest to a niche (national) audience, then the Podcasters will beat local AM stations because of economy of scale.
I can visualize a future for small market AMs doing local content, most of it with minimal "live" presentation. It is going to take some innovative people to squeeze the costs out of content acquisition.
I draw a blank on what we might do to utilize the metro AMs. Toasting marshmallows may win the annual "Genius Award".
And all of this is not just limited to the Carolinas.
