It's Arbitron. They're really okay if you don't mind taking a survey for a few minutes. They send me an envelope in the mail maybe three times a year, it has cash in it, anywhere from 2.00 to 20.00 with instructions on going online to take a survey, or you can answer the questionaire and return it by US mail or wait and they will call you and you can take it on the phone. I don't think I've spent more than a total of 10 minutes on the last couple of surveys they sent me. This latest one will take some time, it's a survey on the radio stations I listen to on a daily basis for a week. I don't mind doing it and I get to have lunch on them.
