There’s no reason for that to be on the airwaves in 2023.
Why's that? A radio show that curates the best of other radio shows is a perfectly fine use of the medium. In fact, it makes a lot of sense as if you like listening to one radio show you will probably like listening to others as well.
Programs like The Sunday Edition, and Writers and Company are gone
Huh? Writers and Company is still there, and is streamed to legacy devices on Sunday at 3PM.
Maybe radio is dying, I don’t know.
Quite the opposite. It is alive and well. That show you spoke of earlier being able to regularly find new content from other radio programs to present to the audience is telling about just how strong radio is. If radio was dying, that show would have died long ago.
