This is the modern version of Disney's practice of re-releasing its animated films in theaters every several years, which began with the 1944 reissue of 1937's "Snow White and the Seven Dwarfs". During the 1980s and 1990s, when the home video market was dominated by VHS systems, Disney films would be reissued every ten years (a time gap equal to that of their theatrical reissues). The moratorium period was continued with the evolution of home media delivery mechanisms, including DVD, Blu-ray, and digital streaming, which Disney itself mainly markets through its own Movies Anywhere initiative. Television commercials for Disney home video releases will alert customers that certain films will be placed on moratorium soon, urging them to purchase these films before they "go back into the Disney Vault", in the words often spoken by voiceover actor Mark Elliot. Some direct-to-video Disney films, among them "Bambi II", have also been released with a pre-established window of availability.
