Encyclopædia Britannica Films

Encyclopædia Britannica Films (also named EB Films for short) was the top producer and distributor of educational 16 mm films and later VHS videocassettes for schools and libraries from the 1940s through the 1990s (by which time the internet replaced video as a primary source for educational media).
