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.
WiFi and Cellular are also OTA … just you can make your own bubble and to interact with the uplink bubble … I mean you can do it with Broadcast radio too but they get mad …
