Do you think its possible to bill content shot in the early 90's as 'retro' or 'classic' content now?

The reason i ask is that im seeing a lot of movies shot in the nineties billed as a 'classic movie' on some cable networks.

Your thoughts, can nineties content now be considered as 'classic' or do you think we should still be using content from the 60's 70's and 80's only?
