The dollar was real. Now they send $5 bill and if you complete the survey (I did and they sent me another $5) legit company been doing tv rating for as long as we have had tv.
I receive about 3 calls a day, every day from this number. Caller ID says Nielsen. I did not answer the first few times expecting they would leave a message, but they didn't. I then blocked the number, but I still get about 3 calls a day. I don't get it.
This was a legitimate call from Nielsen. My household was chosen for their current radio survey. I've done these for them in the past. They send out a booklet and ask you to keep track of the radio stations you listen to during one week and they give you a small incentive in exchange.
