The experience of being entertained has come to be strongly associated with amusement, so that one common understanding of the idea is fun and laughter, although many entertainments have a serious purpose. This may be the case in the various forms of ceremony, celebration, religious festival, or satire for example. Hence, there is the possibility that what appears as entertainment may also be a means of achieving insight or intellectual growth. An important aspect of entertainment is the audience, which turns a private recreation or leisure activity into entertainment. The audience may have a passive role, as in the case of persons watching a play, opera, television show, or film; or the audience role may be active, as in the case of games, where the participant/audience roles may be routinely reversed. Entertainment can be public or private, involving formal, scripted performance, as in the case of theatre or concerts; or unscripted and spontaneous, as in the case of children’s games. Most forms of entertainment have persisted over many centuries, evolving due to changes in culture, technology, and fashion. Films and video games, for example, although they use newer media, continue to tell stories, present drama, and play music. Festivals devoted to music, film, or dance allow audiences to be entertained over a number of consecutive days.
