Doubtful. True they don;t rate near where they did in their day, but they are still regularly top 3 adults 18-34 and top 5 adults 25-54. Jamn' as well, 6+ doesn't look so great, but in the breakdown it does ok.
It all comes down to "Do we make money off of this station, and if we changed, would we make more money or lose money" Ratings really don't matter all that much. National and agencies buy ratings, but if you have a strong sales team that can conceptually sell locally, it's a win, no matter what the numbers are. All ratings are good for are PD & Talent egos.
