Some formats with the most fiercely loyal listeners — urban, country and Spanish-language — suffered in the switch from diaries to PPMs. Arbitron attributed the change to fans having over-reported their time spent listening to those stations in the diaries. (K-VET listeners, under the diary menthod, were famous for their loyalty. Over the years, I talked to numerous K-VET listeners who filled in their entire diary for K-VET, regardless of who else they may have listened to.)
PPM also has shown that most radio listening isn't in weekday mornings (6-10 a.m.), as had been thought, but midday (10 a.m.-3 p.m.): There was more at-work listening than previously reported.
