An act of entertainment is a form of amusement or recreation. Often, the same theme or image will appear across multiple media, indicating that it is familiar to a large audience. This familiarity is a key feature of entertainment, as it allows people to feel connected with the same content and images that they have seen before. Entertaiment also includes the concept of a virtual world where users can interact with one another. This is also known as a metaverse.
Entertaining themes are ones that the brain is evolved to react deeply to, such as backstabbing and murders. This is because the brain was shaped to understand the social world.
