Back when it was the 3 major networks ( ABC, CBS and NBC) they had the fairness doctrine .
If an opinion or conclusion was offered, they had to give "equal time" to the other side.
Walter Cronkite rarely gave his opinion and simply stated the story of the day .
CNN started corporate 24/7 news , soon to be followed by Fox-news , and off we go.
Now, all the news networks need to compete for listeners to bring in ad sponsor $$.
As a result , opinion and editorial is renamed "news analysis" .
Most news shows, now have some form of bias to gain viewers.
It's like the ol' home team broadcasters in sports LOL.
