You can probably sell or donate those old magazines to a collector, or a kid interested in that stuff. At the very least drop them off at a thirft store instead of just dumping them.
The one thing I have in my garage I know someone would want is a big pile of laserdiscs. But, again, a thrift shop (or my library) wouldn't want them and I live pretty far out from a major city. Probably will try Craigslist post-winter though as I'm trying to declutter.
Luckily there are (currently) multiple playlists of it on Youtube.
But they might not be there next year.
