Entertaiment is the art or skill of entertaining. It can be as simple as an amusing book or movie for one individual, to a banquet adapted for two people, or a performance intended for thousands or even global audiences. The word is often associated with amusement, but many entertainments have a serious purpose, such as ceremony, celebration, religious festival, or satire. Entertainments often hit on points the mind was evolved to react deeply to, like social backstabbing or murders for example.
