What is information choice in media communication (gatekeeper)

The janitor theory. Gatekeeper is synonymous with theory, which was put forward by Luis1947. Information always flows along some channels including "doorways". In these channels, it is decided whether to allow information or goods to enter the channels or continue to flow in the channels according to fair regulations or personal opinions of "gatekeepers". (2) Shi Lamu, a master of communication, also pointed out that there may be a huge amount of excluded content between the sender and the final receiver. It can be seen that "gatekeeper" is first of all a right to choose information that can enter the next communication channel. In the current massive news, the problem of news selection is more prominent. The objective facts of mass news are like a double-edged sword in communication technology. On the one hand, people can indeed face more information, but on the other hand, the time for the audience to learn information from the media will not be extended with the massive increase of news, but will face two dilemmas: First, a large amount of information may overwhelm the information that is really useful to the audience, leaving the audience at a loss. Second, in mass news, it is difficult to distinguish between true and false news. Even if news comes from the same true fact, its composition quality is mixed. Therefore, the importance of "gatekeeper" to news selection is more prominent now, and the role of "gatekeeper" of communicators is not simply reduced, but changed.

That is to say, what kind of information can be continuously disseminated to the audience, and gatekeepers are everywhere. For example, news reports, the original gatekeeper is a reporter. He first decides what news he needs, and then editors and even presidents can call them gatekeepers. In other words, anyone who decides the direction of news in a certain link can be called a gatekeeper.
