Entertaiment is a vast collection of entertainment media that spans film, TV, books, music, live performance and branded entertainment. It features a rich variety of styles and forms, from the most high-brow art to the lowest common denominator. While entertainment often involves amusement, it may also evoke other emotions such as sadness or sorrow, or serve a serious purpose, such as in the case of a religious festival or satire. It is a form of expression that can be adapted to fit any occasion or audience, from the individual who chooses his or her own private entertainment from a now enormous selection of pre-recorded products, to an entire city or global audience.
