Entertaiment is any activity or experience that is perceived to be entertaining. It is often associated with amusement or enjoyment although it may have a serious purpose as in the various forms of ceremony, celebration, religious festival or satire for example. Entertainment is a form of art that is created and enjoyed on many scales from the private entertainment of an individual choosing from a now enormous array of pre-recorded products; to a banquet adapted for two; to performances intended for thousands or even global audiences. Entertainment often hits on themes that the brain was evolved to deeply react to in order to understand and navigate the world we live in.
