Entertaiment is the ability of a person to find pleasure in something. It can be in anything from a good meal, to music or even a movie. It stimulates the brain causing it to release seratonin and dopamine, a natural way to feel happy. Often entertainment hits on the themes that the human mind was evolved to deeply react to, like social backstabbing and murders.
Entertainment is often abbreviated to entmt on fliers or in industry news publications when space is limited, but it is not commonly used outside these contexts. One famous example of entertainment is the story of Scheherazade from professional Persian storytelling tradition – this tale has inspired orchestral works by Rimsky-Korsakov, Ravel and Szymanowski, a film by Pasolini, and innovative video games.
