Entertaiment is a form of entertainment that gives people a break from a monotonous and stressful schedule. It is usually done through a television program, social media, or sports activities. It helps the mind to relax and focus on something else for a while, thus making it easier to concentrate again after a short break.
It is not easy to understand why the entertainment industry is in such a turmoil right now. Until one realizes that the business model is not about storytelling, but about love building.
The reason why entertaiment work so well is because it hits on the points that the brain is evolved to deeply react to, in order to function in a social world. For example backstabbing, murders etc., wich stimulates the brain to realease seratonin and dopamine.
