Yes, and ethnic stations tended to lose share when the PPM came to town, and there were two reasons.It could be losses from additional competition from EMF and streaming, but since KCMS is a commercial station, they don't sell as much based on ratings anyway. Local Direct is a lot of Christian-owned businesses or ones who want to reach a local Christian listener base. Those local businesses advertising don't have that opportunity via K-LOVE, which is pure donation-funded.
Pretty sure both of those markets mentioned are diary markets, not PPM like Seattle/Tacoma.
First, Black and Hispanic listeners tended to round to the hour, so listening from 8:12 to 8:48 got "8-----9" in the diary which was 4 quarter hours. In the PPM, they got two quarter hours as neither the first nor the last qualified.
Second, the big gainers in PPM were stations that had both primary listeners and lots of "oh, I listen to them too" listeners. In the diary, those secondary listening times often were not registered. In the PPM, some mass appeal formats got as much as 35% to 40% higher cume, resulting in greater share/rating. But ethnic stations either had their community or not, and little secondary listening. Some lost share in the PPM.
