Any thoughts on the changes or changing Audio names/terms/meanings.

Likely  you can come up with some,  In my  audio lifetime it seems that what was once called "bookshelf" speakers are now "monitors". 

They were always called monitors in pro audio. I think the name bled over to home stereo especially since people hopefully put monitors on stands and not the bookshelf.
LP's are now vinyl. No, vinyl is what your Grandmother had on her sofa in the front parlour.
