Entertaiment is a broad term that encompasses any form of play. It can range from activities that were once practical, such as hunting or warfare, to spectator sports; to a meal for two; to a banquet for thousands; to a performance by a professional troupe; or to an interactive video game. Entertainment evolves and re-emerges from one medium to another, for example the story of Scheherazade has inspired a number of musical works (by Rimsky-Korsakov, Ravel, and Szymanowski); a film by Pasolini; and an innovative video game.
Occasionally you will see the word entertainment abbreviated as entmt on a flier or in industry news publications.
