It was a smart way to drive interest in Disney’s release schedule for DVDs and Blu-rays: Whenever a beloved film emerged from the Vault, consumers, collectors, and resellers would rush to buy it, assuming their opportunities to own it would be limited. For years, the Vault was where Disney put films between waves of releases, so some classic titles would be unavailable for long periods. With the release of Disney Plus, Disney has effectively done away with its fabled Vault.
