Entertaiment is anything that gives a person a sense of enjoyment and pleasure, such as a play, movie, concert, or video game. It may also include sports, dance, or reading.
Often entertainment hits on the points that the mind was evolved to react deeply to in order to survive and understand the world we live in. It can also stimulate the brain to realease seratonin, dopamine and other chemicals.
Entertaiment is able to transcend the boundaries of different media, and many familiar themes, images, and structures have been reinterpreted again and again, in new forms. Entertaiment is often associated with fun and laughter, but it can also have a serious purpose, such as in the case of ceremonial ritual or religious festival or satire for example.
