Being a successful CHR in Little Rock isn't much different than being a successful CHR anywhere else. Stay on top of the music and keep focused on your listeners. That's really all you have to do, though it's definitely easier said than done.
I remember the Zoo 98 and KKYK CHR battle in the late 80's/early 90's. Both were excellent stations, and a lot of markets would have been happy to have either one of them. I remember thinking I would've had either one over Y-95 and KEGL in Dallas. Little Rock was lucky to have both; plus, KLAZ wasn't a bad choice after it moved from 106.3 to 105.9 and upgraded its signal in the process. Unfortunately, both also got caught up in being CHR's when no one wanted to be a CHR. Despite its success, Zoo 98 bowed out first after Encore Broadcasting sold it to George Buck's GHB Broadcasting. KKYK tried like mad to get the Zoo 98 listeners, but maybe they tried too hard. They had constant name and image changes, and their musical direction seemed to change with the wind. I'm thinking they also lost Craig O'Neill during that time, which was the nail in the coffin. So, they bowed out and went full-blown rock.
I was in Little Rock for several months in 1994, which was during those few years when there was no CHR in the market, unless you count KLAZ 105.9. At the time, I was pretty disgusted with that type of music in general. So, it didn't bother me. I seem to remember my dial being glued to the recently-launched 94.1 The Point, Magic 105, Cool 95 and KLPQ/KOUN. I had my clock radio alarm set to KEZQ 102.9, but, aside from the 40 minutes or so it took me to get up and out the door, that was about the only time I ever listened to 102.9. B-98.5 got a sample or two from me here and there, but it didn't really do much for me. However, I guess it didn't need me as a listener as it's done just fine with those 25-54 females!
