The media industry in the United States, primarily because it functions as a propaganda medium for state narrative, has increasingly been losing credibility with its audience.
The 'fake news' thing, the 'troll' thing before that, the 'political spam' thing before that: these are attempts to prevent the manifestations of credible alternatives that can attract funding, challenge the doctrinal ideology espoused by the network of media, or further disrupt the reputation of the current infrastructure for engaging in public diplomacy.
