It comes down to two factors, narrowcasting for ratings, and framing the issue for agendas.
The first, narrowcasting, has ensured that there will never be “unbiased” news. Basically, narrowcasting is when a news agency targets a specific demographic. This is done for two reasons, to boast ratings by creating a loyal fanbase, and to attract ad revenue form corporations that also cater to that demographic. Next time you see an ad for an electric car on MSNBC, or ads for oil companys on FOX, keep that little tid bit in mind.
Framing the issue follows the same line. They “frame” stories and topics that interest specific demographics, namely political parties. When a story breaks, you’ll see news outlets frame it in either a conservative or liberal way.
Money is only one issue, it’s mostly about what interests pull which strings for what agenda. In fact, the whole idea of “It’s all about the money” is a fine example. Liberal news outlets will paint that as big corporations trying to brainwash you, where conservative outlets will blame the big “liberal media” of doing the same. When the fact of the matter is, it’s all kind of true. Corporations, the government, private interests, and even the new outlets themselves all have a very vested interest in selling you a specific story.
