Entertaiment is the act of entertaining others with amusement, diversion, or pleasure. It can take many forms, from a single person reading a book for entertainment to large scale performances intended for hundreds or thousands of people. Entertainment has been known to relieve boredom and loneliness, to inspire and provoke thought, and to provide a sense of achievement. The power of entertaiment is shown by how stories such as the Scheherazade in the professional storytelling tradition have been adapted into orchestral works, films and innovative video games. Entertainment also hits on the points that the brain was evolved to deeply react to, like murders and backstabbings, as it was important for surviving in a social world.
