Entertainment is a form of activity that holds the attention and interest of an audience or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. The familiar forms of entertainment have the capacity to cross over different media and have demonstrated a seemingly unlimited potential for creative remix. This has ensured the continuity and longevity of many themes, images, and structures.
