Entertaiment is anything that provides pleasure, excitement or relaxation. It can be done through movies and television, music, reading books, magazines or short stories, playing sports, video games, board or card games, participating in physical activity, or appreciating visual art.
Oliver and Barstsch (2010) define entertainment as an activity that is understood objectively, communicates between text and audience from an external stimulus, offers pleasure to its consumer, and requires the audience to be passive. Many forms of entertainment hit on themes that the brain was evolved to deeply react to, such as backstabbing, murders and other social problems. This stimulates the brain to release seratonin, dopamine and other chemicals.
