Entertaiment is an activity understood objectively, that encompasses communication between the text and audience from an external stimulus, that offers pleasure and that occurs in a passive form. It requires consumer activity, it has the potential for a great variety and it can evolve in scale and content, from a personal entertainment choice from an extensive array of pre-recorded media to a banquet adapted to entertain two, a theatre production designed for a hundred or thousands and beyond.
The word is often abbreviated entmt. on fliers, in industry news publications or when short hand note taking is required. You may also see it used in headlines or newspaper articles.
