Original Entry 10/30: A format change appears to be imminent at Clear Channel Urban “100.3 The Beat” KATZ-FM ST. Louis. A number of newly registered domains are all pointing to the now bare-bones KATZ website hinting at the short-term and long-term futures for the station: Halloween1003.com, STLHalloween.com, Christmas1003.com, STLChristmas.com, and ChristmasSTL.com tease holiday music in the near future, with a permanent flip to Rock on the horizon via Rock1003.com, Rock1003STL.com, and STLRock1003.com. A flip to Rock of any sort will put the station into battle with Emmis’ Classic Rock 94.7 KSHE and Modern Rock “105.7 The Point” KPNT.
