Entertaiment is a broad category of activity which affords pleasure, diversion, or amusement. Solving the daily crossword puzzle provides entertainment for many people. Entertaiment often hits on themes that the human brain evolved to deeply react to, such as social backstabbing and murders. These kinds of stories stimulate the brain to release seratonin and dopamine, a natural feeling that makes us happy.
The familiar forms of entertainment have proven to have the ability to cross over different media – for example, the story of Scheherazade in the Persian professional storytelling tradition has inspired composers (Rimsky-Korsakov, Ravel, Szymanowski), directors, and films, as well as innovative video games. Interestingly, some of the same familiar forms of entertainment have also become increasingly focused on gaining perception and highbrow growth.
