Salt Lake City and Green Bay aren't exactly "smaller".
Funny thing you should mention green bay in the context of this thread.
Step back in time. I'm a Chicagoan. Born, raised, etc... However, for a few years of my formative life (my late years of high school), my Mother got transferred to a job in small-town green bay wussyconsin. What a freakin' culture shock!
Anyway, the big dog then, as it is today, is 101 WIXX. Back then I think they were more Top 40 than the CHR they claim now, but in that time frame (the mid to late 80's), they pretty much nailed it in terms of music mix and one big thing... Playing new stuff, both mainstream and "out in left field" music that I would NEVER, in a million years, hear here in Chicago on either Z95 or B96 at the time. One of the things WIXX was good at was running the middle of the road on every music genre and hitting the sweet spot. Whereas here in Chicago, all the stations adhere to a more specific demo and tend to go in to certain genre's much deeper. Using the Z95 and B96 examples above, even though they were the two top40/hit radio stations here at the time, it was clear Z95 went more to the rock side and B96 went more to the rhythmic/urban/dance side.
Now with that said, they (WIXX) weren't in the same league when it came to air talent, promotions, production quality, etc vs. a Chicago station. Sometimes listening to the weather update on IXX was painful. It always sounded like the TV meteorologist that they used (A WBAY TV one most likely), sounded like he recorded it on an Optimus cassette deck and sent it (the cassette) over to the air staff. Or Menards commercials... Then moments of dead air between things... Terrible production quality...
I remember recording the Murphy in the Morning show from Q101 here in Chicago at the time, and playing it for my friends in GB. Or at night, Crazy Man Alan Kable on Z95 or Bubba the Love Sponge on B96... Their jaws were on the floor hearing what craziness was happening on Chicago airwaves.
