Guys, I was a TV news producer for five years. Both stations I worked for were corporate-owned. One of them was in the top fifty television markets, in case someone tries the “you were too small for them to care” argument for the statement that follows.
I was the only person responsible for five hours of news programming a week. Not once did I have a “corporate overlord” alter any of my content.
Men in sunglasses looking over shoulders in newsrooms is a myth.
I am absolutely positive that the corporate ownership was concerned about ratings, which translates to dollars. That mainifested itself in the General Manager/News Management of the station making talent and content decisions designed to keep (or increase) the audience. Ideological slant was avoided as it affects the credibility of the news product. If you annoy half your audience with slanted coverage, they will go to your competition.
That’s TV news at the local level. On the national level and in newspapers, ideological bias is easier to see. But we only tend to notice the bias we disagree with. If they lean our way, we hardly notice because our world view is being confirmed.
