As far as AM HD, what the consumers don't want is AM. No amount of
technology can fix the AM band and its old-fart image among most anyone
under about 45. This is why AM listening is declining so fast, and the only
remaining listeners soon will be over 55, a group nearly no agency ad
account wants.

It's true. AM's problem is perceptual rather than technical in
nature, so it would be surprising if a technical solution (AM stereo
or HD radio) would do much to help stem its gradual decline.

AM radio has nowhere to go but more of where it is already: carrying
focused formats with significant but limited appeal that wouldn't fly
on FM. It might continue to be modestly successful in this way for a
long time to come, however, because there are probably just enough
people who will listen to a 24/7 polka station (for example) in a
metro area to fly on AM.

One man's gold is another man's trash. Don't be surprised if many
people tune up and down the AM dial and find little of interest to
them, and never bother with AM again. I suspect that this has already
happened with a lot of less old listeners.
