Hitler and the Nazi party saw media dominance as crucial to influencing public opinion and gaining support for their government. The Nazi party was especially worried about the power of the international press, thus it actively sought to stifle any coverage or criticism that was unfavorable of the regime abroad. The Nazi party was able to provide a one-sided version of events and pass off its propaganda as reality because they controlled the media.
The viewpoint of the typical German citizen would have been negatively impacted in a variety of ways without a free press. Citizens would be more inclined to accept the official party line as fact if they were denied access to varied sources of information and the opportunity to read and hear alternative opinions. This might lead to people not thinking for themselves and being in the dark about what's happening in their nation. Potential negative outcomes include increased obedience and less willingness to speak out against the government. A society suffers when there is less of an opportunity for people to express their opinions and share their knowledge with others.
