Are you aware of the phrase, "conflict of interest?"
Much (mush?) of what you've written there is gibberish, and certain parts are inherently illogical. For example you claim that many independent newspapers are biased, and you know this, but you don't know who owns them. So how do you know they are independently owned? Moving on...
You're correct that advertisers have always been an influence. This is very different than a small group of billionaires having control over all network television. The Reagan administration changed the anti-trust laws which had previously pretty much guaranteed that the people had a voice. Currently Obama is pushing the idea that the Internet should be censored and scrubbed of ideas which are not true. Sounds great right? So who determines what is true? Isn't this a direct assault on constitutional rights?
Back to the topic, it is a conflict of interest for General Electric to tell you what to think about the world situation and also profit from the development and sales of arms. It is a conflict of interest for 15 billionaires to own all major media.
