Entertaiment is a broad category of activities that provides enjoyment, recreation, or amusement. It is usually associated with a sense of fun or light-heartedness, although entertainment may also have serious purposes (such as ceremonies, celebrations, religious festivals, and satire). Some common forms of entertainment include movies and television; music, including attending concerts and playing musical instruments; sports and games; reading books and literature; and visual arts.
Its important to remember that entertainment is a form of art, and often hits on points that the brain was shaped to react deeply to in order to survive and understand the social world it evolved in. This is why some entertainment themes like murders, backstabbing and other social machinations can cause intense feelings of pleasure or excitement in the audience.
