The answer to "media is information" must start from Marshall's cognitive view. In "Robot Bride" (I can only read this, but "understanding media" is too obscure), he pointed out that the essence of mechanical technology lies in cutting, and the essence of automation technology lies in connection. Integration is the basic starting point of Marshall's understanding of media, so he opposes empiricism and criticism, and thinks that media and information are also interrelated. The "content" of any medium is another medium. When you read the same "content" in different media, such as Weibo and news broadcast, when you want to know the "content", you have to use another media. The subordinate media of news is the paper media, and its broadcast mode and writing form all inherit the linearity of the paper media, so the media form is serious, on the one hand, it wants to show its authenticity, on the other hand. . Just to be serious and funny; Weibo's subordinate media is discourse, which makes it close to interpersonal communication and enhances its credibility, which is why people like rumors in Weibo so much. To sum up, you can understand why it is the same news, but the communication effect between news broadcast and Weibo is quite different, and why there are two kinds of public opinions, that is, you can understand the importance of the media to the content, and you can also understand that the media is information.
