Be sure that the sponsors of those shows know what you're doing and why. Otherwise, unless you're a Nielsen household, your not watching CBS won't have the slightest effect except to make you feel better (not that that's a bad thing).
Yeah, I realize that. I spent a good couple of hours today writing to everyone and their mother. There was a good contact list on a thread floating around here. I still have more writing to do though. I'm actually mad at CBS because I really enjoy their Monday night comedy lineup. Oh well. Gotta follow the conscious.
A year ago we got a call wanting to make us a Nielsen household. They were extremely upset when we turned them down.
They even called back, trying to convince us what an honor it was to work for them for free. Barf.
