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.
The same happens with live TV and the amazement of having to accept and watch whatever is being broadcast.
