The National Film Preservation Foundation is a non-profit organization created by the U.S. Congress to help save America’s film heritage. They support activities nationwide that preserve American films and improve film access for study, education, and exhibition.
The process of the Board began in 1992, when Congress asked the Librarian of Congress to assess the state of film preservation. The report issued the next year under the direction of National Film Preservation Board, alerted Congress that motion pictures were disintegrating faster than archives could save them! The films most at risk were documentaries, silent-era films, newsreels, historically significant home movies, avant-garde works, industrials, and independent films-not the Hollywood sound features that had become synonymous with American film. After 4 years of this process and research the NFPF was founded in 1996.
