The National Association of Broadcasters, a trade association that lobbies the interests of various broadcasters in the government. In 1952, it created a code for television broadcasters mentioned in the movie multiple times as a set of rules that make journalism independent and unbiased. However, in reality, the code had a clear bias and forbite discrediting family, God, and law enforcement structures and covering overly hostile and violent topics (National Association of Radio and Television Broadcasters). Hence, the filmmakers knew that there was direct censorship in their code of practice while reassuring the audience of their virtue. They influenced children to believe in media sincerity, disarming them in the face of future propaganda.
