Entertaiment is any activity that diverts or amuses people in their leisure time. It can involve an active participation, such as playing a game; a passive observation, such as watching a performance; or both, as when children imitate adult activities or watch television. Entertainment can take many forms and evolve over time – the story of Scheherazade, for example, is found in professional storytelling traditions, but also inspired orchestral works by Rimsky-Korsakov and Ravel, film directors Pasolini and Bergman, and innovative video games.
