Today, mass media, such as newspapers, TVs, satellites, virtual social networks like Twitter, Facebook, LinkedIn, Telegraph, etc., have a positive and negative impact on relationships and operations in a weird process. From the point of view of international law, the existence of the media is considered to be human rights, and the same is true for the media in terms of politics and democracy. Speech, words, words, texts, forms, and images printed by the media change the view of the audience and this changes the attitude, thinking and behavior of the community. Unfortunately, the media are misconceptions about the tools and tools of politics, which is contrary to the spirit of this human right. The active presence of the media among the community and the proper publication of materials, news and texts, transparency and human look can make society an ideal-human society.
