Entertaiment is a broad term for anything that provides pleasure, diversion, or amusement. Examples of entertainment include watching movies or TV shows, playing video games, or reading books or magazines. It can also include playing sports, attending live performances such as concerts or theater shows, and creating or appreciating visual art.
The word entertainment comes from the medieval Latin phrase intertenere, which means to hold inside: inter- and ten- are both prefixes that mean “inside.” It has since become synonymous with amusement.
People are entertained by many different things, including escapist dramas about murder, backstabbing, and other social events that the brain was evolved to deeply react to in order to survive in a world where others can kill you at any moment.
