Probably the earliest example of support for history education comes from Computer Image. Around 1968, Computer Image collaborated with the Navajo Curriculum Centre to produce a set of films of Navajo morality tales using CAESAR. In the past, these would have been passed on by elders but it was becoming difficult to achieve in the modern culture. The films mostly have Coyote as the central character.
Coyote and the Lizards: 1971
More details can be found in the CAESAR section.
On the 19 October 1972, the BBC Horizon programme had the title When Polar Bears Swam in the Thames.
Colin Emmett produced over 2 minutes of animated spectacular explaining a theory of how the ice ages happened for the programme.
