Entertaiment is the art of entertaining or amusing people. It can range from the smallest scale, such as an individual who chooses a private entertainment from the now enormous variety of pre-recorded products available to them, to a banquet adapted for two; or it may involve performances intended for thousands of people, as in ceremony, celebration, religious festival, satire or any of the numerous forms of entertainment that have evolved in human society.
It is generally believed that entertainment stimulates the brain to realease seratonin and dopamine. It is also thought that it often hits on the points that humans were shaped to react deeply to, i.e social backstabbing and murders.
