Entertaiment is a word used for a lot of things, from the clown at a party to the Broadway show to the stadium rock concert to your friends fighting over the last potato chip. It’s a term that has a variety of uses, and it comes from the French word for entertain, meaning to keep happy or amused.
Many of the themes that appear in entertainment hit on the points that our brains were evolved to react deeply to, such as murders and social backstabbing. These themes are a result of our natural desire to understand and participate in the world around us.
