Different media representations bring, into the spotlight, different views from different people with different beliefs and opinions. Different media might be funded by different companies or individuals with different intentions so you can get an idea of what those intentions are when you observe what the specific media is showing, how it is showcasing certain news, how it is showing certain individuals like politicians, celebrities, etc. One political debate would be viewed differently across multiple news channels, across multiple news anchors and across multiple social media platforms and posts.
