The filmstrip was a common form of still image instructional multimedia, once commonly used by educators in primary and secondary schools (K-12), now overtaken by newer and increasingly lower-cost full-motion videocassettes and DVDs. From the 1940s to 1980s, filmstrips provided an easy and inexpensive alternative to 16mm projector educational films, requiring very little storage space and being very quick to rewind for the next use. Filmstrips were large and durable, and rarely needed splicing. They are still used in some areas.
