Yes, SCART is a European invention, although I think it has now spread to other parts of the world, North America excluded.

Standard banana plugs were also once very common on much equipment here, although for domestic radios etc. a smaller "split-pin" type of plug was used, commonly known as a "wander plug." They were often found as antenna and ground connections on 1950s radios.
