The Finlux televisions at the end of 1970s introduced colour television for common people. The purpose was to make Finlux's OBC series a ”people's car” that is, a television that suits for every home and the use would be easy even for the ”old granma”. Vaajakallio's job was to define the operation principles of the regulating unit. The picture shows drafts of Finlux OBC TV 20” 22” and 26”.
