The word “entertainment” has a broad and varied definition, encompassing any form of entertainment that provides amusement or pleasure. It can range from a simple joke told to a friend, to a complex play or musical performance intended for a large audience, to an artistic exhibition or public service announcement. Interestingly, many forms of entertainment have a long history and have been recycled again and again in different media.
It is believed that entertainment hits the points that our brain was evolved to react deeply to, such as social backstabbing, murders and other themes that were important in a human society. Entertainment can also stimulate the brain to realease seratonin and dopamine, wich give a good feeling.
