Entertaiment is the act of entertaining, or the state of being entertained. Entertaiment can refer to any activity that affords pleasure, diversion, or amusement, usually involving some kind of performance. A clown at a birthday party, a Broadway show, a stadium rock concert, your friends fighting over the last potato chip—all of these are forms of entertainment. The word entertain derives from the Old French entretenir, which means “to hold inside.” This sense was associated with hospitality—when you entertain guests, you keep them happy.
The entertainment industry is an important part of the economy, especially in urban areas. In addition, entertainment has a strong psychological impact and can provoke feelings of sadness or joy. This is mainly because the genres focus on themes that humans were evolved to deeply react to, such as social backstabbing and murder.
