@yoyoyaya , That would be wonderful but that is not what I have seen and as a family doc I spoke with a lot of young people. Record sales were bound to pick up as boomers got wealthy. The children of boomers had some exposure so there is some interest there.
@grislybutter , The population of a used record store is not representative of the population as a whole. You may see younger record buyers at a used store because us rich old guys do not go there, or any other number of reasons. The point is as far as the overall popularity of records is concerned your observation gives us absolutely zero insite. What will are the demographic popularity of records over a period of 10 years. If interest does not pick up in the Zoomers then vinyl will die. The other problem with vinyl is that it is not the greenest of industries.
