I do not think BriWi will, in the end, survive. The economics of TV news and the increasingly unpredictable finances of the networks mean that they keep doing news in part for reasons of prestige and you cannot be a prestigious prevaricator, no matter how fun that phrase is to say out-loud. If he does, and there is a non-zero chance he will, it will be the final crowning proof that the public are actively rejecting their civic duty to take news seriously and consume it critically and responsibly so they can make good democratic choices. I’m not sure that needs any additional proving at this point but there you have it.
Should BriWi go away? It’s not as easy a question as it sounds. Obviously, his credibility has been seriously tarnished but is that a necessary skill for his job? When was the last time anyone took the Main Evening News shows seriously? The format was already on the way out way back in 2004 when it was hit by the 1-2-3 sucker-punch of the death, retirement and discrediting of Peter Jennings, Tom Brokaw and Dan Rather. It never recovered. What difference would it make if he did go? It would not make NBC Nightly News matter again, there is no force on heaven or earth that could do that.
