If you define death as the very last AM signing off, then, yeah, you might have 20 years, but that final 5-7 is going to be more like walking dead than alive.
There is a great expanse of land between the coasts that cannot be covered by FM due to its shorter range. AM is the only feasible technology there and that goes hand in hand with the sale of F-150's and Chevy and Ram pickups. No way will they take AM out of those vehicles. Out in the boonies AM is perfectly serviceable.
I have AM in my car but never use it unless I am out in those same boonies looking for something to keep me awake. When closer to home I listen to FM HD. But it isn't so much the technology that drives what I listen to, it is the content. There is no content on any AM in my metro area that I want to hear (KOY was the last bastion of good AM radio) so I listen to FM.
If AM dies, and I don't question that it will eventually, it will be because radio station owners let it die. Failure to provide popular content, poor signals, revenues not providing enough profit, antenna farm properties being more valuable for condos than antennas etc. It will probably die first in the major metros but it will take a lot longer out in the sticks because FM cannot replace AM and I don't see cell phones doing so either.
Well, first of all, it's getting a lot harder to find large stretches of road without some FM signal. Especially in the flatter parts of the country, a good FM's liable to reach 100-125 miles. You pretty much need 50kw and a good dial position to do that without noise on AM.
And when you're dealing with someone under 50, if there's no FM, and no reliable data service, they're probably going for the few hundred or thousand songs in their phone (or, if they're retro-friendly, CDs) before they ever punch up AM.
I'm 57, and I haven't listened to an AM station by choice unless I knew it was an exceptionally good station since 1969. And I think the last time I felt that way about an AM station was...a long time ago.
