The technology was a kludge, with inferior audio quality and serious interference problems, especially on AM. And the premise was flawed... Thus there is simply no marketplace need for "HD radio," and it has been rejected by retailers and consumers. It will soon go the way of quad FM and AM stereo, or be used for non-audio data services.
But while it's true when David Eduardo says, "FM HD offers... a lot of opportunities, particularly for
narrowcasting and much better fidelity versions of what would be on SCA channels otherwise," I really
don't see that happening now in market #4. The HD-2 fare is plain blah, or duplicating other stations.
No money is being put into the HD-2 product, from what I can hear...
Plus, not all of the Bay Area can receive the HD-2 signals, let alone the HD-1 signal, as is the case where
I live, due to the Bay Area's hilly terrain. I don't see the L.A. Basin having that problem...correct me if
I'm wrong...
Even the HD-2 on the oldies station in Newport, Oregon, is duplicating 1230 KCUP...
This article from last September says it all about HD:

As John Gorman says: "The (HD) Alliance is leaving the future of HD Radio in the hands of the station owners."

TV digital broadcasting, however, is mandated by law. Like it or not, over-the-air television will be digital, and unlike radio, the frequency allocations are different. The old frequencies are either to be sold to the highest (non-broadcast) bidder, or used by police and fire departments.
But will AM, as I fear, also become moreso of that George Carlin line from his great 1967 recording, "Wonderful WINO"?:
"1750 on your dial, just above the Police Call Scan!!" (but going further left on the dial)...
I'd like to believe I am as optimistic as JoshuaEscandon on AM Radio's future, however...but it takes
money and quality-programmers to make it work, and those factors are simply not there for AM anymore...

In 1990, a government agency, CBS Labs and others got together to provide a way for radio stations to operate digitally. The original idea was to use a satellite, that would approximate a station's current analog coverage.(Eureka 147) This concept was well underway in parts of Europe. When they tried to put it into effect in this country, the US government refused to relinquish the band that would have made it possible(L-Band) because it was(and is)being used by the military.
The Eureka 147 was supposedly the way to go, too...
And whatever became of the Acorn DAB system that was demonstrated at the 1991 NAB Convention?
Being I'm not technically-inclined, can someone offer why that system did not take off? Same reason
for the end of the Eureka 147 here in the U.S., perhaps?
