A form of entertainment is an act or event intended to provide amusement, enjoyment, or diversion. It often involves humor, a sense of adventure or suspense, or a spectacle to draw attention. In many cultures, the concept of entertainment has evolved into a broader sense of leisure or recreation, involving a wide range of social activities. Many of the world’s most familiar forms of entertainment have been around for centuries. They often evoke a sense of mystery and can be transformational for individuals or groups. This is especially true in the case of movies, novels, and music. It is sometimes difficult to discern between high-brow entertainment and aesthetic effect and low-brow exploitation or coarse entertainment.
