The gatekeeper theory was first put forward.

The gatekeeper theory was first put forward by American social psychologist Kurt Lewin.

Gatekeeper theory was first put forward by Kurt Lewin (1947), a famous American social psychologist and one of the four founders of communication studies, in the article Channels of Group Life.

Lei Wen believes that when studying group communication, the flow of information is carried out in some channels with "gated areas". In these channels, there are some gatekeepers, and only information that meets the group norms or gatekeeper value standards can enter the communication channels. 1950 white, a communication scholar, introduced this concept into the field of news research and clearly put forward the "gatekeeper" model in news screening.

The information control of traditional media is completed by gatekeepers at all levels, and "gatekeepers" are in a dominant position in determining the media content of traditional media. Network is a decentralized "new interactive media".

There is no fixed concept of disseminator in network communication, and the difference between disseminator and addressee is decreasing. Network communication makes the former gatekeeper lose the privilege of information dissemination, and the traditional role of gatekeeper is gradually weakening.
