Entertaiment is a broad concept that encompasses all art forms and activities that provide relaxation or enjoyment. It can range from the childish or the trivial to the sophisticated or cerebral. Different individuals prefer different forms of entertainment, for example, a comedy show when feeling down or a documentary when in a contemplative mood. Creative entertainment often seeks to provoke complex emotions, such as joy, sorrow, or suspense, and to challenge the intellect by presenting alternate viewpoints or by requiring problem-solving and strategic thinking.
