I am mid-40s. My daughter is 11. I take her to school, among other driving things, and usually play NPR. Whenever she needs to refer to what she's hearing -- usually to ask if I'll turn it off so she can pull up some godawful thing where a random Youtuber squawks discordant lyrics to a Pokémon video game score -- she calls it a podcast. I've stopped correcting her, particularly since most of the "shows" release as podcasts by the next day anyway.
I wasn't even all that in-tune with my own generation, so seeing my peers' preferences recede into the haze of "the olden days" has occasionally been a bit of a relief and reset The idea of actual radio being baffling is amusing though.
