Nielsen wrist-slaps station for ratings-oriented survey question.

A cautionary note: Radio station WWWQ/Atlanta included a question in an online form to loyal listeners, “If you are asked to be in a radio ratings project that required you to carry a device that recorded all of your radio listening, would you do it?” That question earned them a special notice from Nielsen, saying, “Recipients of WWWQ-FM’s email may perceive that the station has an interest in PPM participation. This in turn could differentially prompt the station’s listeners to agree to participate as PPM panelists, or differentially sensitize panelists to wear or carry their meters while listening to WWWQ-FM.”
