CBS has switched 95.7 KKHH to an Adult Hits format, as "95.7 The Spot" with "Your Place, Your Music, Your Way" as the slogan. But CBS owns Jack-FM stations all over the country, Los Angeles, Dallas, Seattle, Minneapolis, using the slogan "Playing What We Want." It uses Howard Cogan as its Jack voice. He's even based at KCBS-FM LA.
Yes, I know Jack was on 103.7 some years ago, and wasn't much of a success there. In fact, it still carries the KHJK (Houston's Jack) call letters. But it only uses them at the top of the hour, as an Air 1 Christian Rock affiliate. I'm sure most listeners don't even know this info.
So why invent a new Adult Hits format for Houston? CBS is clearly happy with Jack in four other cities.
