Entertaiment:

What’s fun for one audience may not be entertaining to another. That may be why so many familiar forms of entertainment — movies, music, books and plays — have found their way into multiple media over the years. The word “entertainment” is derived from the Medieval Latin intertenere, which means “hold inside.” That echoes the Indo-European root ten, meaning to stretch or extend something.

Entertainment often hits on the points that the brain was shaped to react deeply to in order to understand the world around us. For example, it’s easy to find stories about social backstabbing and murders in the entertainment industry.
