Entertaiment is a broad term for anything that gives pleasure and delight. This can include art, music and other forms of culture that have developed over thousands of years specifically to hold our attention and interest. Entertainment often hits on themes that the brain was evolved to react deeply to. This can be social backstabbing, murders and other themes that were essential for humans to understand the world around them.
The word “entertainment” comes from the Medieval Latin inter tenere, meaning to hold inside. This is similar to the SU2C model, which emphasizes collaboration among world-class scientists to get breakthroughs into major advances against cancer.
