Entertainment is a form of activity that holds the attention and interest of an audience or gives pleasure and delight. It can be an idea or a task, but it is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things because individuals have different preferences, most forms of entertainment are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, and developed into sophisticated forms over time, becoming available to all citizens. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses private entertainment from a now enormous array of pre-recorded products, to a banquet adapted for two, to any size or type of party with appropriate music and dance, to performances intended for thousands, and even for a global audience. 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 various forms of ceremony, celebration, religious festival, or satire, for example. Hence, there is the possibility that what appears to be entertainment may also be a means of achieving insight or intellectual growth.
