Entertainment is an event, performance, or activity designed to give pleasure or relaxation to an audience (although, for example, in the case of a computer game the "audience" may be only one person). The audience may participate in the entertainment passively as in watching opera, or actively as in computer games.
The playing of sports and reading of literature are usually included in entertainment, but these are often called recreation more specifically, because they involve some active participation beyond mere leisure.
The industry that provides entertainment is called the entertainment industry.
