The term for shortwave radios targeting the general consumer market is "world band radio". They look like a standard portable AM/FM radio except they'll also pick up long wave, medium wave, short wave, and maybe weather band. They're more of a niche in the US now that internet streaming is a thing, but you should still be able to get one at most electronics stores. Of course like most niche products, you'll get much better selection and pricing online.

I used to have little battery powered AM/FM/Shortwave/weather radio lost it a couple house moveings ago. Kept it around for the emergacy weather radio during flood events and other extreme weather when internet/power isnt reliable. Should probably pick up a replacement come to think of it.

I'm in the US. At least half of the people I know own shortwave radios, although most don't think of them as "shortwave radios". They're more often called "world radios" or some other such synonym. I could run out to a consumer electronics store right now and buy one.

The younger people I know tend to own such a radio in the form of the Baofeng UV-5R or the like.

def a niche consumer item these days. but pretty easy to make your own.
