First off, what is gatekeeping? Wikipedia states that Gatekeeping is the process through which information is filtered for dissemination, whether for publication, broadcasting, the Internet, or some other mode of communication.
The theory of gatekeeping was theorised by the late Kurt Lewin in 1943. His concept was “The Gatekeeper decides what information should move to group or individual and what information should not. Here, the gatekeeper are the decision makers who letting the whole social system. The gatekeeper is having its own influence like social, cultural, ethical and political. Based on personal or social influences they let the information to the group. Through this process the unwanted, sensible and controversial information’s are removed by the gate keeper which helps to control the society or a group and letting them in a right path”.
A lot of things in the media go through gatekeepers to stop certain information that doesn’t or shouldn’t belong in a certain group. For example some politicians will gatekeep what information they don’t want their audiences to know.
Personally, I think gatekeeping was a smart call from Lewin as some boundaries are needed on some topics.
