| With the advent of the "omnimedia era",the daily life style of the masses has undergone tremendous changes.Technology promotes the innovation and development of communication media,and social media,as the most mainstream at present,has become a "field" that people cannot escape from for work,life and entertainment.Although science and technology provide a lot of convenience for people,it also gives birth to many new social problems at the same time.Social media is rich in information and diversified in content,so that the audience can not only get timely information,but also make real-time comments and express opinions.However,in recent years,in social media,some people get away with the anonymity system in cyberspace and the imperfect accountability mechanism,so they wantonly distort the truth of news,constantly strengthen and polarize their personal views,distort the social value orientation in the name of "criticism",and constantly influence others’ judgment and mislead the public.The phenomenon of non-reflective "criticism" is constantly spreading in social media.If we want to correct it in time,we have to think of making a profound analysis with the help of the Frankfurt School’s media criticism theory,and find solutions based on the social reality.The body of this paper is divided into three chapters.The first chapter sorts out the development process of traditional media to social media,and reviews the transformation of communication media from the historical dimension.Then it analyzes the reasons why social media are so popular at present,which are the arrival of the "omni-media era" and the wide demand for information after the mass material living standard has been greatly improved,as well as the strong psychological dependence of the masses due to the entertainment property of social media itself.The most typical social problems caused by the non-reflective "criticism" of social media are "irrational cathartic","Internet violence" and "media trial".In the second part,from the perspective of Frankfurt School’s critical theory of media,the author holds that mass culture is the inevitable product of cultural commodification,and the media is the tool to continuously extend and develop this result,and to subtly and gently manipulate the psychology of the audience.Marx’s "alienation" theory and Lukacs’ s "materialization" theory are the foundation of media criticism theory.German fascist totalitarianism and American monopoly capitalism are the realistic background of media critical theory.The main contents of the critical media theory of the Frankfurt School come from: Adorno’s "culture industry" theory;Marcuse’s "false demand" theory;Benjamin’s "mechanical replicationism" and Habermas’ s "public domain" theory.The third part not only opens up a new path of media critical research with the Frankfurt School media critical theory;It created a new Angle of view for the study of Marxist theory.Enriches the new connotation of popular culture theory;The historical achievements and contemporary values are the premise for solving the realistic problems in today’s society.On how to solve the social media of reflective "criticism" hot problems,make public criticism appeals to reason,by using mass media critical theory horizon,cultural industry characteristics of the public’s maneuverability,such as fraud and today’s social media audience be manipulated and deceived comparative analysis,to find their identity and inner link,and put forward the solution,Thus guiding public criticism is based on the premise of reflection. |
