Yesterday held the release of Arbitron’s Fall book’s first Arbitrends covering NYC for August, September and October (diary). WHTZ-FM and WLTW-FM are tops in P12+, respectively–the same ranking as PPM data released earlier this month. WCBS-FM P12+ went from 3.7 in Summer trends to a 4.2 in the Fall trends. WFAN was stable from Summer to Fall trends at a 2.6 share. WCBS-FM, like we noted in the Long Island numbers, is stronger in both PPM and Diary. WFAN-AM and WAXQ-FM were two of the bigger losers in comps for diary–higher in PPM, lower in diary. ‘FAN should be of interest, as well, because of the differences in LI and NYC.
