Entertaiment is a broad term that encompasses many forms of leisure. It can range from the purely recreational activities that children enjoy (through play and imaginary friends), to performances staged for spectators or global audiences. It can also include skills and actions that have evolved from their use in hunting or warfare, such as archery or fencing, and can be used for sport or satire. The concept of entertainment has become so broadly defined that what is considered entertaining to one person may be regarded as work or cruelty by another.
