Disney has used the "vault" for theatrical showings since 1944, when they reissued Snow White and the Seven Dwarfs, though the last film actually re-released in theaters was The Lion King almost a decade ago. (Nowadays, a film is "released" from the vault to a reissue of home media (like Bluray).

Eisner was mostly responsible for changing vault releases to home media sales (like VHS or DVD) instead of theatrical releases.
