Supplemental context

Test cards were functional images that also became part of everyday television memory. The Science Museum Group's record explains their role in checking picture settings when programs were not being shown. Its Test Card F generator belongs to the BBC Heritage Collection, and the card's central photograph showed Carole Hersee with a toy clown. For future readers, this is a reminder that broadcasts included maintenance and waiting as well as scheduled entertainment. A pattern designed for technical work could become familiar enough to be remembered as part of a viewing culture.

Creator/community: Broadcast engineers and television audiences; BBC Test Card F as the named example Place/era: Television test imagery; Test Card F used from 1967 into the late 1990s
