Entertaiment is a complex and ever-evolving concept. Activities that were once part of hunting or war have become spectator sports; and familiar stories, such as the one about Scheherazade – an active professional storyteller in the Persian folk tradition – have been retold in many different media. Entertainment can be personal, such as an evening at home with a DVD or digital video game; or large-scale, from a banquet to a performance intended for thousands or even for a global audience.
