Media psychology is the branch and specialty field in psychology that focuses on the interaction of human behavior with media and technology. Media psychology is not limited to mass media or media content; it includes all forms of mediated communication and media technology-related behaviors, such as the use, design, impact, and sharing behaviors. This branch is a relatively new field of study because of advancement in technology. It uses various methods of critical analysis and investigation to develop a working model of a user's perception of media experience. These methods are used for society as a whole and on an individual basis. Media psychologists are able to perform activities that include consulting, design, and production in various media like television, video games, films, and news broadcasting. Media psychologists are not considered to be those who are featured in media (such as counselors-psychotherapists, clinicians, etc.), rather than those who research, work or contribute to the field.
There are overlaps with numerous fields, such as media studies, communication science, anthropology, education, and sociology, not to mention those within the discipline of psychology itself. Much of the research that would be considered as ‘media psychology’ has come from other fields, both academic and applied. In the 1920s, marketing, advertising and public relations professionals began conducting research on consumer behavior and motivation for commercial applications. The use of mass media during World War II, created a surge of academic interest in mass media messaging and resulted in the creation of a new field, communication science (Lazarsfeld & Merton, 2000). The field of media psychology gained prominence in the 1950s when television was becoming popular in American households. Psychologists responded to widespread social concerns about the children and their television viewing. For example, researchers began to study the impact of television viewing on children's reading skills.
