Entertaiment is the enjoyment of some activity that gives pleasure and forgets all the troubles. It can be a piece of music (either live or recorded) or art, a movie, a theatre play or just having a good time with friends. It can also be a sport, or even an act of humour. Entertainment is a huge business that provides pleasures on any scale, from one-to-one private entertainment, to banquets and parties of any size, to performance for thousands. Many forms of entertainment have proved to be enduring, for example the story of Scheherazade, from professional Persian storytelling tradition, has inspired orchestral works by Rimsky-Korsakov, Ravel and Szymanowski; film directors Pasolini and Woody Allen; and innovative video games.
