Content: Once the storyline has been set, updates are forced into the narrative. After the story, the news media requires some time to lapse (what I like to call the "goldfish pause") before it can reinvent the participants in new roles. As a result, news that contradicts the storyline is less likely to be aired until after the "goldfish pause". Fairness Bias
The act of trying not to be biased creates a bias. ( No one said remaining impartial was going to be easy!) The journalistic code demands fairness in reporting, and many news media outlets manage this by trying to add balance to every story. In particular, this affects coverage on politicians and politics. To prevent being biased to one side, the media often seeks a reaction from the opposing camp. As a result, new policy always looks controversial and politics always seems contentious. New positive policies or announcements are routinely undermined by the media, who feel compelled to seek an opposing view, which might become more influential than it should by dint of its media coverage.
