Entertaiment is a word that has many different definitions, but generally, it refers to something that provides pleasure or diversion. It can also be a means of social interaction, and it may be serious or humorous. It can be on a small scale, such as a private entertainment, or it can be on a larger scale, such as a play or a performance. The term is often abbreviated to entmt on fliers or in industry news publications when space is limited.
In my opinion, entertainment should always have a light at the end of the tunnel. It should provide joy and dopamine, but not be overly sexuaized or give the impression that it is all about backstabbing, murder and other social issues that our minds were evolved to react deeply to.
