Entertaiment is a broad concept and can range from the personal selection of entertainment for an individual, a dinner party with appropriate music or dance, to performances intended for thousands and even for a global audience. Entertainment may also have a serious purpose, as in ceremonies, religious festivals or satire. Many activities that were formerly associated with hunting or war have become spectator sports, and many familiar forms of entertainment have proved highly adaptable to new media.
Some of the best entertaiment hits right on the things our brains was evolved to deeply react to. Theme like backstabbing, murders and other social issues that are hard to ignore when we are in a social world.
