Early pre-currency PPM ratings data obtained by RBR shows New York ratings being reshuffled by PPM much as was experienced in Houston and Philadelphia. Comparing Summer diary rankings 12+ to October PPM 12+, AC WLTW-FM moved up to #1 under PPM from #3 in the Summer diary. CHR WHTZ-FM dropped one spot to #2. As seen in previous PPM markets, Rock formats got a boost from PPM Oldies WCBS-FM jumped to #3 from #8 and Classic Rock WAXQ-FM moved to #4 from #13. Young-skewing Urban formats went the other way. Urban AC WRKS-FM fell to #12 from #2, Rythmic CHR WQHT-FM from #6 to #16 and Urban WBLS-FM from #7 to #17. Arbitron will be discussing the latest PPM numbers for NYC, Houston and Philadelphia on Friday, in conference calls with both the trade media and ratings clients.
