* Parents buy cheaper DVDs for their very young children...Children who care less about display quality.
* While travel plummeted during middle of pandemic, there were still people who took road trips (e.g. maybe for staying with family, etc.)...and during those roadtrips, i'm sure some families opted for DVDs and DVD players instead of trying to stream stuff while on the road, etc.
* Many folks buy cheap DVDs, because their favorite movies stop being available on their current subscriptionsof streaming servicews. I hate this myself. So, my partner bought 3 or 4 of their favorite movies, so we can watch them whenever we want - even if we lack internet (though we would need power for the dvd player of course)
* Vinyl records have their followers who revitaliuzed the format...so maybe there are collectors of DVDS...?
I'm sure there are other reasons for why this is happening.
