Entertaiment is a type of cultural production that provides an experience of pleasure. Entertainment stimulates the brain to realease seratonin, dopamine and other chemicals. This can give the feeling of a good feeling and may be important to the way humans evolved to understand the world around them. Alot of entertainment hits on themes the human mind was evolved to deeply react to, like social backstabbing and murders.
Oliver and Barstsch (2010) defines entertainment as an activity understood objectively that communicates between text and audience from external stimulus, offers pleasure, requires an audience to exist and occurs in a passive form. Entertainment can be adapted to any scale, from a private entertainment choice by an individual; to a dinner party accompanied by music and dance; to performances intended for thousands or even a global audience.
