Entertaiment is the activity of entertaining or amusing people. It encompasses activities such as theatre, music and games and focuses on pleasure. Although technology alters the availability, cost and variety of entertainment products, many forms remain recognisably unchanged. For example, the story Scheherazade (from the Persian professional storytelling tradition) has inspired many retellings – including orchestral works by Rimsky-Korsakov and Ravel; films; and innovative video games. Entertaiment is sometimes abbreviated to entmt on industry news publications and fliers, where space is limited.
