Lucky! I had to do a nielson survey a few years ago and it was just filling out a notebook every night. I like to think I had a significant part in bringing up TechTV's numbers that quarter. Considering the tiny number of nielson respondents, I probably did.
The Nielson ratings system is now portable. It's not a device that is bolted to my TV or radio. Radio and TV programs are now encoded with an inaudible ID. The programs that I watch can be rated regardless if I watch it live or DVR it. It also works in the car or wherever I go. The data is uploaded every night when I put it in the charger.
I don't have access to any data, but I wish that I could see the numbers to know how my viewing and listening habits are affecting rating. I am very careful about channel surfing now. I might be responsible for more scifi and supernatural related TV programming, although I wasn't able to save Surface or Invasion.
