Entertaiment consists of activities involving enjoyment and amusement. It may range from a private entertainment experience, such as a movie for two or dinner for a group of friends, to performances intended for an audience of thousands. It also includes ceremonies, celebrations, and religious festivals; sports and games; and forms of satire and parody (1,2). The word entertain has evolved to include the sense of amusement that people have with one another and their environment. People often take a competitive or professional attitude toward their involvement with entertainment, but it is important for them to consider the business side of the industry as well (2,3).
