Entertaiment is a broad concept, encompassing many different forms. Despite this, some themes, images and structures have become familiar across media. This has ensured the longevity of entertainment and the capacity to continually reinvent it. Entertainment can be adapted to any scale: from an individual choosing their own private entertainment, from the banquet adapted for two, through to entertainment suited to thousands. The word entertain derives from the Latin intertenere, from the prefix inter and the root ten. The root ten comes from the Indo-European word ten, meaning stretch or extend. The resulting stretch is a key component of most entertainment.
