Entertaiment is a collection of popular cultural artifacts and artforms that have exhibited a remarkable capacity to cross over different media. This has enabled familiar forms to have a surprisingly infinite amount of creative remix potential, guaranteeing the longevity and ongoing popularity of many images, themes and structures. The experience of entertainment often feels like leisure, even though it is not necessarily without cost. It can involve a great deal of psychological and emotional investment. Some types of entertainment may also have a serious purpose, such as religious rite, political and non secular pageantry, or satire. Some of these can have highbrow value, if they address points the human brain was evolved to deeply react to.
