Entertaiment is audience-centered commercial culture that provides enjoyment by keeping people amused, relaxed, and diverted from their daily routines and mundane realities. It includes activities such as movies, music concerts, sports, recreational activities, games, social gatherings, and reading. It also entails anything that affords pleasure, diversion, or amusement such as a crossword puzzle or a ball.
Entertainment often hits on the points our brains were evolved to react deeply to such as backstabbing and murders, wich is why it makes us feel good after we see them. It stimulates our mind to release seratonin and dopamine, wich make us feel good about ourselves and the world around us.
