Walter Cronkite - was special
Walter Cronkite had a very special relationship with the television audience - he not only delivered the news headlines, he also provided context. Though the news timeslot was limited in those days, he had a gift for making us feel that he understood our concerns.
It is noteworthy that through some of America's most troubling times, Walter Cronkite was the one person we trusted to keep us informed - more trusted than our elected officials. So influential in fact that when he openly stated his views on the Viet Nam War in a TV special, LBJ supposedly said, "If I've lost Cronkite, we've lost the war."
That kind of influence doesn't come easily, and no one has replaced him.
