Entertaiment is the repurposing of traditional forms of entertainment to meet new demands. It can be as simple as a single individual watching a movie on his or her own, to a dinner party accompanied by music, to an elaborate banquet for many people, or even to events intended for thousands and more. Entertainment can also be a serious experience, as is the case with religious festivals or satire. Entertainment often hits the points that the brain was evolved to understand and react deeply to, like social backstabbing and murders. These themes can evoke feelings of fear, empathy or sadness.
