I did not mean to suggest it is new. In fact, I think in a post long, long ago about the introduction of "Happy News" on WABC-TV in Noo Yawk I suggested we were on a downward spiral into nonsense news.
I remember that this was when ABC Moved Roger Grimsby from KGO-TV San Francisco in the late 1960's to WABC-TV where Al Primo introduced happy talk to NYC Audiences for Eyewitness News/ Newsscene and Russ Coughlin the then KGO-TV GM put Van Amburg and Jerry Jensen to take over Roger Grimsby's San Francisco seat to do the same thing in San Francisco until the 1980's.
