Entertaiment is an experience of amusement, laughter or arousal. It can take the form of entertainment for a small group or audience, or it may be a serious performance or activity that carries a deeper purpose and is intended to achieve insight or intellectual growth. Whether a particular form of entertainment has a formal or informal purpose, it usually takes the form of an event that involves music and dance. It can also include activities that are performed as a spectator sport, such as fencing or archery, or by professionals who perform as a team for a large audience. Often these forms of entertainment have the potential to cross over media and be used in other contexts, such as a television program or live concert.
