Entertaiment is an important and enduring part of human culture and society. It is reflected in a wide variety of forms and can be found throughout the world and across time: from a private entertainment for two; to an activity adapted to any size group or occasion; to performances intended for thousands or even global audiences. Entertainment also displays a remarkable ability to cross over media and be remixed, with themes and images remaining constant while structures evolve and adapt to suit different purposes and audiences.
