The radio ratings that are freely available on the web are called "12+" or "top-line" ratings. They mean nothing to advertisers, and that's why you don't need to pay to see them. 25-54 numbers, especially 25-54 numbers for specific parts of the day, are what really interest advertisers and more accurately determine a station's success. But in the case of KPOJ Portland's switch to "Progressive Talk," the 12+ numbers at least show the trend. Here's a list of all of Portland's talk radio stations, and their 12+ ratings for winter and spring:
12+
CALL WIN SPR CHNG
KEX 5.3 4.2 -21%
KXL 4.7 4.0 -15%
KPOJ 0.4 3.7 +825%
KPAM 2.0 1.6 -20%
KOTK 1.8 1.3 -28%
And in the ever-important 25-54 demo, KPOJ rose from a 0.3 to a 4.9, putting them in the #3 slot overall for all Portland radio stations, according to an industry publication, and putting them ahead of all other talk stations in the market. (This contradicts even rosier information I received earlier. I trust this trade pub more.)
Particularly impressive is that, in the 25-54 demo, KPOJ's 10a-3p daypart (2 hrs Franken, 3 hrs Ed Schultz), scored a 6.4, putting KPOJ at #1 among all Portland radio stations, which means KPOJ cleaned the clocks of both Lars Larson and Rush Limbaugh.
Even more amazing is the month-by-month breakdown of that 10a-3p daypart. Again in the 25-54 demo, KPOJ grew from a 0.4 in March, to a 4.9 in April, to a 5.5 in May, to an unbelievable 8.8 in June.
