Entertainment is an event, performance, or activity designed to give pleasure 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.
In Edutainment, entertainment and education blend together to make learning easier.
The industry that provides entertainment is called the entertainment industry.
Recreation, play, reading, and art appreciation are not generally regarded as entertainment but rather as recreation because entertainment generally requires the supplier of the performance to be visible to the viewer, with the exception of computer games.
The entertainment industry (much of which is informally known as show business or show biz) consists of a large number of sub-industries devoted to entertainment. However, the term is often used in the mass media to describe the mass media companies that control the distribution and manufacture of mass media entertainment. In the popular parlance, the term show biz in particular connotes the commercially popular performing arts, especially musical theatre, vaudeville, comedy, film, and music.
