TED Talks

721–768 of 2,913 films, free to watch, from the world's open archives.

Where these films come from, and who sees what

Every film here plays from the archive that keeps it: the Internet Archive, Wikimedia Commons, the NASA Image and Video Library, the Library of Congress and Open Images (the Netherlands Institute for Sound and Vision). Nothing is copied to this site. Each film's page names its archive, links to its page there, and states its licence or status as the archive does.

Archive films carry no age ratings, so each is placed from the collections it sits in and the subjects the archive gives it, cautiously. Sexual content and nudity are left out altogether.

Little OnesFilms for young children by name: nursery rhymes, lullabies, preschool.
KidsCartoons and animation, children's and family films, and educational films, unless they deal with war, propaganda, crime, horror or drugs, or carry racial caricature.
TweensDocumentaries, science, nature and space, classic comedies, newsreels, commercials and lectures.
TeensEverything else, including anything we cannot tell about; war, crime, horror and westerns go no lower.
AdultSexual themes (such as the old "sex hygiene" films), gore, surgery, slaughter, atrocity footage.
