Well, "younger" in this case would be people in their 40s and 50s, I would think. Some of those people might have 97.1 preset, but I don't think Audacy is expecting a significant 18-34 audience for news.Just for fun, I wonder how many former listeners will still have 97.1 on their preset and discover KNX and actually listen? They said they are going for a younger crowd. My boss still has 980 AM on his car preset (along with 640 and 1070 AM) even though he doesn't speak a word of Spanish.
On the other hand, anyone like your boss with the same car and the same presets could have 97.1 set from the "Free FM" or Stern/Leykis days. And they'd probably be in their 40s and 50s.
