Comcast owns NBC. TBS and Time Warner Cable own CNN. The Walt Disney Company owns ABC. The list goes on and on.
There is this thing called the 1st Amendment. It explicitly prohibits a state run media. Just because you disagree with what someone says doesn't mean that it's state run.
You also seem to be extremely ill informed of media history. There has never been a time in our nations history - EVER - when the media was not biased. I encourage you to read up on how newspapers saw their role throughout the 18th, 19th, 20th, and 21st Centuries. Modern day news is sheer child's play compared to how things were reported one or two hundred years ago.
