Cultivation theory in its most basic form, suggests that television is responsible for shaping, or ‘cultivating’ viewers’ conceptions of social reality. The combined effect of massive television exposure by viewers over time subtly shapes the perception of social reality for individuals and, ultimately, for our culture as a whole. Gerbner argues that the mass media cultivate attitudes and values which are already present in a culture: the media maintain and propagate these values amongst members of a culture, thus binding it together. He has argued that television tends to cultivate middle-of-the- road political perspectives. Gerbner called this effect ‘mainstreaming’. Cultivation theorists distinguish between ‘first order’ effects (general beliefs about the everyday world, such as about the prevalence of violence) and ‘second order’ effects (specific attitudes, such as to law and order or to personal safety).
