I still love listening to my old phonograph vinyl records.

I used to have a lot of records. I can't believe the phonograph was invented back in 1877.

As of 2017 there were only 48 record pressing facilities remaining in the whole world, only 18 in the United States.

Wow. That is crazy. They were originally commonly made from shellac. They didn't start using polyvinyl until the 1950's.
