Origin:The theory was developed in the 20th century by Paul Lazrsfeld,Bernard Berelson, and Hazel Gaudet while studying the 1940 U.S. presidential election.
Concept:
通过这个模型，我们可以清楚地看到，它表明信息不是由媒体直接传递给公众的，而是有两个步骤：
1.Information first reaches influential individuals, who then consume media content and interpret the information
2.These influencers then pass on their understanding and views of the message to their social circle or their audience, who then pass it on gradually
Conclusion:This theory emphasizes that interpersonal relationships play an important role in shaping public opinion, not directly determined by the media. It shows that people are more influenced by the people around them who know and trust, not just the media
In my opinion, this theory still has great disadvantages when applied to the present, because it may not be in line with the modern media environment. This theory puts too much emphasis on the role of opinion leaders and takes other factors into consideration. For example, each medium has different life experiences and values
