Just heard someone on a YouTube video tell viewers to "stay tuned" for something coming up later, and I'm struck by how some phrases outlive their initial context. Literally, it makes no sense to say "stay tuned" on YouTube, but everyone still knows what it means and thinks nothing of it, even people who have probably never actually watched a TV channel via terrestrial transmission.

@scalzi I try not to say it when I have the presence of mind about it, and instead subtitute a "stick around", but yeah. "Stay tuned" is "stay here". Heck, even on TV, "stay tuned" was well past its expiration. I'm 38 and have never "tuned" a TV, just changed the channel.

Anyway, let me "roll down" the window in my car for some fresh air...
