It was Howard's decision. I can't blame him for wanting to talk almost non-stop and I'm sure it's great for Beth that he talks to someone else every once in a while. Someone of his status definitely deserves the right to end things on their own terms.
Monday: Show
Tuesday: Sternthology. Whatever Howard talks about Monday, they play related archival material here.
Wednesday: Wrap-Up Wednesday.
Thursday and Friday: Archival material. It seems this will be random stuff.
Thursday: Monday's show (and maybe other stuff?) appears on HBO Max. Based on the preview, it sounds like there'll be lots of old stuff. Go into HBO Max, type "Howard" and you'll see a preview.
The gaggle of stuff on the app still exists.
And yeah, I'm glad I got my $4/mo (with bonus item) plan. It's essentially $50/yr for a Bluetooth device and the radio is in someone else's car as a Christmas present.
