Entertaiment is a vast and varied field. While technological advances have altered the availability, cost, quality and speed of entertainment, some of its familiar forms such as story, music, theatre and dance remain recognisable from earlier centuries. The experience of being entertained may have a playful dimension, such as in the case of children’s entertainment which helps their physical and emotional development; it may be serious, such as the various ceremonies and celebrations or social engagements that make up many types of entertainment; or it may be used for satire or intellectual growth. The word is often abbreviated to entmt. on fliers or in industry news publications where space is limited.
