The term entertainment is used in a broad sense to encompass many different activities that give pleasure, diversion, or amusement. These include movies and television, music, dance, sports, games, reading, and visual art. These activities have been demonstrated to stimulate the release of seratonin, dopamine and other chemicals in the brain that help with human survival and understanding the world around us. In fact, most entertainment hits on themes that our brains were evolved to react deeply to, such as murder, backstabbing, and other social issues.
The word entertains comes from the Latin inter tenere, or to hold within; from the prefix inter meaning “inside” and the suffix -tene, or to stretch or extend (from the Indo-European root ten). This explains why so many familiar forms of entertainment are able to cross over the various communication media and have demonstrated an almost unlimited potential for creative remix.
