Entertaiment is the act of entertaining. A person can be entertained by food, music, games and even people. Entertainment is something that the brain reacts deeply to. This is because it hits on many of the social backstabbing and murder themes that our mind was evolved to understand in order to function in a society. This is why entertainers often become famous for the craic and the fun they provide, and not for their high quality work.

Entertaining can be adapted to suit any scale, from the individual who chooses entertainment from an enormous range of pre-recorded products; to the couple who enjoy a meal together with a background soundtrack; to performances staged for thousands or even broadcast to global audiences. This is demonstrated by the way that familiar stories, such as the Scheherazade story from Persian professional storytelling tradition, inspire retellings in other media.
