Entertaiment is a broad category of activities and entertainment products that provide pleasure, recreation or amusement. It includes entertainment like theatre, music and movies but also other activities such as sports, games and reading. While technology has changed the supply and demand of entertainment, many forms have remained the same for centuries. For example, the story of Scheherazade from Persian professional storytelling tradition has inspired countless musical compositions (including by Rimsky-Korsakov, Ravel and Szymanowski), films and video games.
