Received a call this morning from Nielsen. Had to answer a TON of questions about my TVs, Tivo, AV Equipment, ages of people in the house, income range, cable company, cable package we have, etc. After it was done the lady said we'd receive an agreement soon in the mail that we needed to sign and return to them. Looks like we'll be one of the new Tivo/Nielsen families soon. Has anyone else gotten this call - and if so, how far has the process proceeded?
