Representation involves how people, places, and objects are portrayed to an audience through various media. Representation is unavoidably selective and constructed from a particular point of view. Various theorists have examined how representation works. Stuart Hall analyzed how audiences can interpret representations in preferred, negotiated, or oppositional ways. Richard Dyer examined how stereotypes are often used to brand groups and present differences as natural. Roland Barthes distinguished between denotation and connotation, and how myths are conveyed. Laura Mulvey introduced the concept of the "male gaze" in film and how audiences are positioned as male viewers. Later theorists like Angela McRobbie and David Gauntlett examined how gender and identities are socially constructed through various media representations.
