There is a recommended diary here that says
If you want better media, support better media
Our individual choices sometimes, but rarely, have an impact. It is true that I am heartened by the fact that the ratings of Faux News is declining.
But it is rare that our individual choices in media combine to have any real impact. It would be more important if we did things like:
Break up the chains in newspaper, radio, TV station & cable TV ownership
Make license renewal for radio and TV stations a real event instead of an empty formality
Strengthen public radio & TV
Put more tax money into financing good movies as is done by the Canadian Film Board
Reinstate the Fairness Rule for broadcasting
Support Net Neutrality rules on all levels of government so that all internet content is dealt with equally
None of those changes create good content in media, but they all add to the number and diversity of voices. Making all public media more like the internet, where there are multiple voices, makes it harder for the creation of the echo chamber effect we often get in the MSM.
