In the current era of digital age, the use of social media is growing day by day and people are having access to social networking sites on a single click. This trend is also giving rise to a public discourse on platforms related to different types of events, such as politics and entertainment. The situations like filter bubbles and echo chambers are influencing the people and they are also affecting the public discourse. The aim of the study is to explore how “Echo Chambers” are influencing the public discourse in online sphere. This study also explores key factors and tools involved in Echo Chambers which are making the sub groups in online sphere. On top of that, the public political discourse on social media is either open or biased. In this study the method of literature review is opted to gain the insights into the research problem mentioned above. Three studies were taken from different countries, including U.S.A, Poland, Hungry and Thailand, to see the impact of echo chambers in different political systems with diverse audiences. In the result, it was found that echo chambers confirm the previously held beliefs of the audience regardless of demographics and the countries. People who are influenced by echo chambers prefer to interact with and follow the people with a like-minded mentality. Moreover, they try to keep themselves from opposing views or opinions. However, for this study the sample taken was small, so it is difficult to generalize the findings. The content available for this topic is scarce and there are no tools from which the effect of echo chambers can be measured before and after entering the chambers.
