And this is not unusual. When the diary was still used in major markets, I did at least three or four annual visits to what was then Arbitron in Columbia, Maryland. Here is an example of the kind of thing I saw much more than once:Impressive.
In a diary from a “senior“ in Chicago, I saw listening to a talent who had not been on WGN for many years listed by that person as having been heard on a daily basis on WIND. The only problem was that WIND had been a Spanish station for nearly a decade at that time and had never had that particular talent in any case.
Well, this example may be written up to a “senior moment“ it is a good example of how people fill outrating diaries. While the top 50 markets, with a couple of exceptions, use the PPM, nearly 200 markets use the diary and we continue to see this type of listener confusion. However, such instances are relatively few if each individual survey. In each individual market that they do not affect the outcome of the overall ratings. But, again, this type of peculiar diary entry can, and does occur.
