This document discusses theories around the effects of media on audiences. It describes the passive audience theory, which suggests that audiences have little resistance to media influence. It also discusses cultivation theory, which proposes that repeated exposure to violent media can desensitize people and make them think violent acts are normal. As an example, the document discusses the 1993 case of two 11-year-olds who killed a toddler, apparently inspired by a horror movie. The document also covers the active audience theory, which argues that audiences actively choose what media to consume. In the end, it suggests that both passive and active effects can influence people to different degrees.
