Read the following passage and write about the similarities and differences between tradition and social media in 4-6 sentences. Traditional media means newspapers, magazines, radio, TV, etc. On the other hand, social media means social networking sites like Facebook, Instagram, LinkedIn, etc. The traditional media vs. social media consideration brings us to a major difference between both. The center of attention of social media is to let people or users of it connect with known and unknown people. On the other hand, traditional media focuses on keeping people aware of various things such as politics, international affairs, etc. All information disseminated on traditional media goes through multiple layers of fact-checking. Also, the information gets produced by authorized journalists or reporters only. Therefore, all information shared on this type of media is absolutely true and reliable. Information on social media is often generated and disseminated by users. Therefore, the reliability in terms of truthfulness is dicey. It can be true and it can be false. Spreading rumors and mocked pictures are common on social media nowadays.
