There is a new Eton radio with AM FM SW LW and DAB, perhaps it's using one of the chips mentioned in the article. The problem is, who's really going to buy such radios?
Younger people are getting their radio programming via smartphones and online streams, and over the air radio is eventually going to fade away.
I don't see radio completely disappearing for a couple decades (at least here in the U.S., where the government is loathe to declare FM and AM dead, like governments have in other countries) -- if only due to population growth and immigration.
