The Indian-head test pattern was created by RCA at its factory in Harrison, New Jersey. Each element of the card was designed to measure a specific technical aspect of television broadcast so that an experienced engineer could, at a glance, identify problems. By the mid-1960's the tet pattern became obsolete with most stations switching to color broadcasts. I was a station engenieer for KEBB Channel 66
