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 sincerely hope that the people can reclaim the airwaves and a new fediverse-like ecosystem springs up for over-the-air broadcasts.
