Industrial films

Sponsored film, or ephemeral film, as defined by film archivist Rick Prelinger, is a film made by a particular sponsor for a specific purpose other than as a work of art: the films were designed to serve a specific pragmatic purpose for a limited time. Many sponsored/ephemeral films are also orphan works since they lack copyright owners or active custodians to guarantee their long-term preservation.

The genre is composed of advertising films, educational films, industrial videos, training films, social guidance films, and government-produced films. While some may borrow themes from well-known film genres such as western film and comedies, what defines them is a sponsored rhetoric to achieve the sponsor's goals, rather than those of the creative artist.

Sponsored films in 16mm were loaned at no cost, except sometimes postage, to clubs, schools, and other groups. AT&T was for decades one of the most active sponsored film distributors; others included airlines who offered travelogues on their destinations. Local television stations also used them as "filler" programming. Some distributing agents packaged films from various sponsors into TV programs with titles like "Compass," "Color Camera," "Ladies' Day," and "Adventures In Living."

The films are often used as b roll in documentary films, for instance the social guidance film The Terrible Truth (1951, Sid Davis) appears, desaturated, in Ron Mann's Grass (1999) as an example of what he perceives as hysteria over drug abuse, as well as an example of the slippery slope fallacy.
