Entertaiment is the word used to describe activities or events that bring pleasure and enjoyment. You might abbreviate it to entmt on a flier or in industry news publications where space is limited, but it is not generally used in general writing.
One of the most famous examples of entertainment is the story of Scheherazade, a professional storytelling tradition in Persian culture. It has inspired orchestral works by Rimsky-Korsakov, Ravel and Szymanowski, a film by Pasolini, and an innovative video game.
