All commercial news is most definitely biased towards their biggest payers that is just logical. They are not going to print unflattering news about their customers and so the commercials stations tend to give minority groups the best press ie their biggest payers and whatever agenda their owners have.
A simple fact in the world, those with the most money get the what they want from commercial stations.
ABC on the other hand has no advertisers and so can show the news the ways it happens. It is not beholding to any corporate entity.
The ABC is not in business to make money that is the whole point. It is not governed by the corporate entities. This is why a lot of politicians want it gone.
