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.
Not surprising. I’m 36 and it feels strange when someone talks about “radio”, “over the air”, “cable tv” and similar old technologies. It’s only been like 10 years since those still existed but it already feels like ancient past.
Can’t speak about everywhere in the world, but broadcast media is pretty much dead. Radio still exists because of cars, but even that is moving towards streaming.
