Entertaiment involves engaging in activities that are entertaining, amusing, or enjoyable. It can range from child-centred play to sophisticated entertainment for adults or groups. Some activities, once used in hunting or war, have been transformed into spectator sports – for example, fencing or archery. Other activities have become part of the entertainment industry – for example, the story of Scheherazade in the Persian professional storytelling tradition has been adapted for music by composers such as Rimsky-Korsakov and Ravel; film and video games.
