Entertaiment is any activity that gives pleasure or amusement. Its forms change over time and can range from the sedentary enjoyment of television or tablet computers to active participation in sport, music, dance, theatre or feasting. Even activities used for hunting or war, such as archery and fencing, can develop into spectator sports or global competitions. Entertainment also prepares children for adulthood by teaching them social interaction and motor skills through play, and it can be both passive and participatory.
