The Cumulus CHR stations are in pretty small markets except for KRBE and Q100. Guidance is really important in this kind of situation, as you are often dealing with new PDs or PDs without a great deal of experience. Jan Jeffries comes from smaller markets and had some huge successes in places like Roanoke. Larger markets have more local decision making (although in every case the mantra is "follow the research and the chart"), but still have guidance: at Cumulus it's Jan Jeffries, at other companies it's a consultant (which Jan Jeffries is the Cumulus consultant)
Let's see where Cumulus is winning in CHR:
Q100 is beating Star 94 in Atlanta
KRBE (104.1) is beating Hot 95.7 in Houston
Hot 101 is beating Q92 (WDJQ)/Canton in Youngstown and is also beating 95.9 Kiss FM in 12+ and 25-54
Q92.3 is beating Z102.9/Cedar Rapids in Waterloo
Hot 104.7 is beating KKCK (99.7)/Marshall, MN in Sioux Falls
In the Quad Cities, All Hit 98.9 flipped to K-Love and B100 is the winner.
In Bismarck, Y93 went AC and Hot 97.5 is the winner.
In Mobile, if they thought CHR could make more money than country, Hot 104 would've forced WABB (97.5) out of format.
WWKL (Hot 92) is beating both 99.3 Kiss FM and WLAN/Lancaster in Harrisburg.
Tower 98.3 was beating 92.5 Kiss FM in Toledo in the 18-34 demo and will beat Kiss again.
KROC (106.9)/Rochester, MN beat 98.7 Kiss FM in Mason City, IA so they flipped it to Kiss Country 98.7
KROC is beating Z93 (WIZM)/La Crosse, WI in Rochester
