In the 1980s we downloaded games from the radio

From my subjective experience, having "been there at the time", I think this was sufficiently obscure that "not really a thing" is not an unreasonable take. It's a bit like "Yes, in the 2020s we got NFTs tattooed on our bodies".

Edit: Although having just googled it it seems like NFT tattoos might be more of a thing than I was aware, so what do I know.

It was 'big in East Germany' though (see my comment about Prof Dr Horst Voelz). A translated section from that link:

"The response to the show was unexpectedly overwhelming. Over the course of the approximately 60 episodes, the station received a total of approximately 50,000 letters from listeners. This was unprecedented in the history of broadcasting."

...and of course as a teenager I was eagerly awaiting each show and recorded the programs that were broadcasted at the end :)

Eh, I was a little too young to be there at the time but your experience sounds infinitely cooler than a NFT tattoo which just might be the lamest thing I've heard in my life and I feel worse about the world for learning about.

It's probably obscure, but anyone from that time would find it plausible because we know both radio and computers used cassettes.

So for me, this title was "Yeah, I get it how that would work".

For fun I just asked my 16 year old son "Do you think it was possible in the past to download a computer game from the radio?". He thought is was impossible, and had no clue how that would work when asked further :D. It totally confused him because "you can't play games on a radio".

Those were indeed different times.
