Dan Curtis was a prolific American television producer whose name became familiar to viewers through long-running daytime and primetime dramas, while Metromedia was a major American broadcasting and production group.

Creators now reuse it less for its original corporate purpose than as a shorthand for old television, giving modern videos an instantly recognisable retro finish.
