Entertaiment has become strongly associated with amusement, as in fun and laughter, although it may have a serious purpose (such as a ritual or religious festival). It can take many forms and can be adapted to any scale—from a single person choosing a movie from a large library of pre-recorded products; to a romantic dinner for two; to a performance for thousands; to an architectural structure devoted to entertainment. It can also include activities formerly used in hunting and war, such as archery or fencing, which have developed into spectator sports. The art of entertainment is constantly evolving and adapting to the needs of a changing society.
