Cultivation theory is a sociological and communications framework designed to unravel the enduring impacts of media consumption, with a primary focus on television. At its core, the theory posits a compelling hypothesis: individuals who invest more time in watching television are prone to perceive the real world through a lens aligning with the prevalent depictions in television messages, in contrast to their counterparts with lower television viewership but comparable demographic profiles.

George Gerbner was a professor of communication and the founder of cultivation theory. He taught at Temple University, Villanova University, and the University of Pennsylvania.
