Media as education. Information, persuasion, education. Pure information has no bias. Pure persuasion is all bias. Education is a mixture of information and bias.
News reporters talk about being objective.
News reporting can be fair, however, consciously presenting all sides of an argument in a neutral way. News presents information in an entertaining way. Most of what we know about our culture comes from the media, and the people we listen to have learned most of what they know from the media. Media is the ocean, ideas, information, culture, images are all fish swimming in the ocean. Competition of ideas.
