Many years ago (30+?) I was a Nielsen “family”. That was when all I watched was network news. (Yeah, I know ...) So I wrote down all the news shows that I watched, and then in the back in the “comments” section, I let them have it about what I thought about network TV. Never heard back, and was never asked again to contribute.
I’ve gotten the little book, and five bills, too. I’ve done the survey three times over the years. I actually think the first time, probably, thirty years ago, they gave three dollars. Guess they’ve adjusted for inflation.
