<P> Gatekeeping is the process through which information is filtered for dissemination, whether for publication, broadcasting, the Internet, or some other mode of communication . The academic theory of gatekeeping is founded in multiple fields of study, including communication studies, journalism, political science, and sociology . It was originally focused on the mass media with its few - to - many dynamic but now gatekeeping theory also addresses face - to - face communication and the many - to - many dynamic inherent in the Internet . The theory was first instituted by social psychologist Kurt Lewin in 1943 . Gatekeeping occurs at all levels of the media structure--from a reporter deciding which sources are chosen to include in a story to editors deciding which stories are printed or covered, and includes media outlet owners and even advertisers . Individuals can also act as gatekeepers, deciding what information to include in an email or in a blog . </P> <P> Gatekeeping is a process by which information is filtered to the public by the media .
