The Library of Congress is working to convert many 1950s through 1970s TV shows to digital files.
According to The Washington Post, the preservation project is a major undertaking. An hour of vintage programming could require almost a mile of videotape. Every inch of that tape must be cleaned and inspected before attempting playback and conversion.
Without the conversion many shows are in danger of extinction, warns Ken Weissman, supervisor of the film preservation laboratory at the Library of Congress Packard Campus.
