Entertaiment is a broad term that covers many different types of entertainment. It can range from watching a movie for one person in the privacy of their own home to an audience of thousands at a concert. Entertainment can also include social backstabbing, murders and other themes that our brains were shaped to react to deeply.
The word entertain comes from the Medieval Latin inter tenere, which means to hold within. It is related to the Indo-European root ten, which means to stretch, so it is fitting that TEN stands for Transformational Entertainment News. Interestingly, familiar forms of entertainment have been able to cross over various communication media and remain popular for long periods of time.
