Entertaiment is the act of consuming entertainment, usually in the form of music, dance, games and other forms of cultural production. It is often associated with fun and enjoyment, but may also have a serious purpose such as ceremony, celebration, religious festival or satire. It may be for an individual or a group, and it is available in various scales including private, bespoke products; small events such as banquets or parties with music, dance and other appropriate forms of entertainment, or performances intended for thousands or even a global audience. During the past several centuries, the availability, cost, variety and quality of entertainment has changed dramatically with the introduction of television and the convergent technologies that have come to the fore in the 21st century.
