These were big-ish news when I was studying back in later 70s, but I never hear of them any more, are the pretty much obsolete now?

Yes.
There were an analog technique for storing/delaying (for a very limited storage time) analog signals.
Now it's more efficient (with infinite storage time) to use A/D and D/A converters with digital storage/delay.

They led to the development of CCD's. I worked on characterizing bucket brigade devices when I worked in an R&D lab in the late 70's. They were interesting devices.
