Entertaiment is an umbrella term for a great variety of activities, events and spectacles. These can be personal and intimate, such as the choice of a DVD for two; they may involve groups of friends or family; or they can be large scale, such as a performance for thousands or even a global audience. Often what is considered entertainment has a serious purpose, such as ceremonial and religious festivals or the use of satire. In other cases familiar activities that were once used in hunting or warfare have been adapted into spectator sports and then become entertainment. For example the famous story of Scheherazade, from the Persian professional storytelling tradition, has inspired musical works by Rimsky-Korsakov and Ravel, a film by Pasolini and innovative video games.
