Media effect theories and social cognitive theories of gender development posit that young people use the media to learn how to behave according to their gender. This study aimed to investigate reciprocal relationships between adolescents’ television diets and their endorsement of hypergender orientations (i.e., hypermasculinity and hyperfemininity). Based on data from a short-term longitudinal survey among 1,007 Dutch adolescents (13-17 years old), this study showed that different television genres were related to hypergender orientations in different ways. The most notable finding was the relevance of reality TV docu-soaps for both adolescent girls’ and boys’ hypergender orientations. In addition, more frequent exposure to romantic comedy movies predicted an increased endorsement of hyperfeminine gender roles among girls, whereas more frequent exposure to situational comedies was associated with lower levels of girls’ hyperfemininity. These findings could be used in media literacy interventions targeting the influence of specific types of television exposure on adolescents’ stereotypical gender role notions.
