Ali Author wrote (and copyrighted) a children’s book entitled My Mother Is the Best Swimmer in the World. The story was based on a Russian folktale told to her by her own mother. Years later, the children’s TV show Coco Melon televised a skit entitled “The Quickest Swimmer in the World.” The Coco Melon version took place in a different locale and had fewer frills, but the sequence of events in both stories was identical. Has Coco Melon infringed Ali's copyright?
