They're still around in some incarnation! Apparently they got bought by Arçelik, a Turkish household appliances manufacturer, in 2007.

Here in the Netherlands, they now have a large range of cheap things, from button cell batteries to earbuds to remotes, cables, flashlights, cameras, navigation systems, you name it.

It's all ridiculously cheap (competitive with Aliexpress prices and sometimes better). Quality is not always great, but not as bad as it could be, and some things I've gotten are surprisingly well built (competitive with things 10-20x the price.) For example, a flashlight I got for 0.99€ with a solid metal construction that's survived whatever I've thrown at it so far.

And yes, they still make radios! Much lower quality, and not shortwave, but still.

They're still around only as a name for the owning group to slap on cheap Beko product.

The Grundig with the well deserved reputation for absolute top of the line quality and build is dead and gone.

I've got an AM-FM radio with an auxillary input that's still going strong since around 2007. How'd you find the owning group / what products they're rebranding?

The grundig site has a Beko UK security certificate! I'm pretty sure the Turkish group renamed some of their old Beko electronic divisions, including radio, to Grundig after the takeover. Not sure about appliances as Beko already had decent presence at the cheap end of the market, so Grundig was maybe a chance for them to try to move upmarket a bit.

Takeover was around 2007 so you could possibly have one of the last "proper" ones. No idea which particular products or if any old Grundig products survived a while longer. What shows up in search now is nothing like the type or quality I'd have once expected of the brand.

I remember selling Beko products back in my electrical retail days (around 2007 in fact). FWIW they were cheap and cheerful but not absolutely terrible quality at the time. Probably a step up from most of the supermarket own brands. Not sure how the company has progressed since then.
