Entertaiment is amusement, usually involving a performance. A clown at a birthday party, a Broadway show, a stadium rock concert, your friends fighting over the last potato chip–all are entertainment. It comes from the Old French word entretenir meaning to hold together or support. Entertainment often hits on the themes that our brains were evolved to deeply react to, like social backstabbing or murders. It can include visual, audio, and even literary entertainment. It can also include playing games.
