Entertaiment is a broad term that can refer to anything from a play or movie to an event at a restaurant or bar. It can also be used to describe someone who is an entertainer like a musician, athlete or influencer. Entertainment can have a negative connotation or it can be viewed as a form of art. Entertainment often hits on the areas that the human brain was evolved to deeply react to. It can include backstabbing, murders and other themes that can make people uncomfortable when they see them portrayed on TV or in movies.
Entertaiment is sometimes abbreviated to entmt. You may see it on fliers or in industry news publications where space is limited.
