Entertaiment is an activity intended to give pleasure or amusement. It is a wide category that can be as personal as a choice of movie for two, or as grand as a theatrical performance or global competition. Entertainment evolves, and activities that were once used in hunting or war may be reworked as spectator sports; skills such as archery or fencing can be honed into professional performances, or even into television competitions with global audiences. The power of entertainment is demonstrated by the way that familiar themes or images can inspire retellings in another medium, such as music, film and video games.
