Ah so its perfectly OK for them to allow "news" that is established (and that they happen to agree with) but any and all other outlets need to be shut out? Seems to me like you're promoting a monopoly. Tell me, was CNN et al considered MSM when they started out?
That's something I can tell a story about.
My first wife's brother-in-law is Kenley Jones, the former NBC foreign correspondent who used to bring the Vietnam War into the living rooms of America, then who later gained continuing fame for stories like the Wayne Williams Atlanta child murders. Jones is based in Atlanta and he got an offer from CNN when Ted Turner had first started operating it out of the ramshackle headquarters at WJRJ-TV, Channel 17.
Kenley said that the major media networks (ABC, CBS, NBC, PBS) all joked and called it "Chicken Noodle News", but the moment CNN started covering the 1991 First Persian Gulf War, the jokes about chicken noodles stopped abrubtly.
Kenley stayed with NBC because he liked his working arrangements as they were but he said he learned a lot watching them (CNN) take off the way they did.
So did the major news networks.
It is important to understand that, since around 1985 or so, news departments are tasked PRIMARILY with generating ratings and posting a profit, so as long as PROFIT is the main goal, you are going to have to struggle to find objective and nonbiased content because news departments will simply continue to create the kind of content that THEIR studies show that their viewers WANT.
Sounds fair and businesslike but it's in conflict with the OBJECT OF JOURNALISM ITSELF, which is supposed to be a PUBLIC SERVICE and which is supposed to exist only for the facts themselves, not a pre-baked focus group study of viewer preferences and beliefs.
The term "mainstream news media" is supposed to stand for any outlet that is able to provide journalism with as much objectivity and as little bias as possible.
PROFIT puts that goal at cross purposes thus creating an adversarial relationship between journalists and owners.
What so many of you are interpreting as bias is really just different ways of catering to the corporate bottom line.
