Media psychology is a branch of psychology that focuses on the interaction between human behavior and media/technology. It examines all forms of mediated communication and how people use, design, share, and are impacted by various media like television, video games, films, and news. Mass media has a significant influence on many aspects of human life by potentially affecting views, beliefs, knowledge, and even voting behaviors. Noam Chomsky identified five "filters" through which mass media operates - ownership by corporations seeking profit, reliance on advertising revenue, influence by media elites and powerful groups, consequences of going against the prevailing narrative ("flak"), and attempts to create a common enemy to unite public opinion.
