And while they tried to DRM it, the DVD standard still ended up having to maintain compatibility across all readers and discs, but for bluray they regularly deprecate older readers who no longer can play newer movies because new releases use new encryption keys which the old readers don’t have access to (and for this reason the PS consoles are the best bluray movie players because Sony keeps them updated)
