NBC Spews has not been respected since the early days of Hunley-Brinkley and newscasts were 15 minutes long. When the 'News' departments were moved under entertainment, and they became 24 x 7, they took it upon themselves to "interpret" the news for the weak minded and then it was a short jump to manufacturing the news.
Chet Huntley was definite center right, while David Brinkley was a sort of wry liberal who didn’t trust anyone in government too much either way.. No one on the air today who compares to these two.
