A unique format that wasn't attracting an audience [in Atlanta].
The point is that no new all-news station has succeeded in any market ??????
WCBS, WBBM, KYW, KNX WINS, XTRA …
Do you really mean NO all-news station in any market has been successful, i.e. their billings have supported them, and their ratings were not in the basement in the last 10 years? I don't believe it. They may not have been the No. ! stations but there must be some that are doing well enough.
You seem to be saying that only established, legacy, all-news stations are viable, and that no one anywhere has been successful with the format since 2006.
And I again understand you have a strong distaste for the format but I think there may be some distortion of the facts.
And remember in 1972-1973 Atlanta had an all news station, WYZE, but it was daytime only and couldnot have been expected to survive.
