Entertaiment means any act, performance, or game intended to divert, amuse, or delight an audience. It can be as simple as a joke, or it may take the form of a play, drama, or opera. The genres of entertainment vary widely, but they share certain characteristics: they are often ephemeral and prone to remix, reinterpretation, or reuse. The forms of entertainment have also demonstrated an amazing capacity for recurrence and persistence across different media. This has ensured the longevity of many themes, images, and structures.
