I worked with the Missouri Historical Society years ago to archive some footage I’d shot of the St Louis city streetscape. It was all on digital video, but the archivists insisted on converting it to an analog medium (u-matic video tapes). Their reasoning was that all media degrades, but that analog at least degrades gracefully. Magnetic tape has the capability of sitting in storage, untouched and un-cared-for, and still be quite viewable with minimal degradation. Digital media becomes corrupted very easily, and requires constant replication and backups, which can be very expensive for massive archives. For media that may or may not ever be touched again, why not pick a medium that requires the least amount of maintenance?

Dear hiring managers: this scenario would probably make an intriguing interview question.
