A form of diversion or amusement: a crossword puzzle; a ball. From Middle English entretenement, from Medieval Latin inter te meaning “inside,” + Latin tenere, stemming from the Indo-European root ten.

Entertainment has become a widely used, and highly valued form of culture in all societies. It can be anything from a single private moment in front of a television set, to a party adapted for two or more people; from an entire festival intended for thousands; to a piece of theater designed for an audience of millions.

Bates and Ferri (2010) define entertainment as an activity understood objectively, involving communication between text and audience from an external stimulus, which offers pleasure, requires an audience to exist, and occurs in a passive form.
