One of the red bits in Upstate NY. If there's a Nielsen box anywhere Upstate I'd be amazed :)
And now that I think about it, I wonder if NBC's affiliates had anything to do with this...
However, looking at my map, apart from the Buffalo DMA, the rest of upstate NY, viewing measurment would be recorded by Diary-Only (Watertown, Albany, Syracuse, Elmire, Utica, Binghamton, Rochester DMAs, etc.)
We had a Nielsen box when I was a kid. They called us up and asked if we had disconnected it because we rarely watched TV.
They came out and took it.
I guess our watching habits couldn't justify selling airtime, so we didn't really represent a section of Americans they wanted to acknowledge.
