Yeah, in the past Neilson (sp?) ratings could only poll selected households and then extrapolate that to the populace at large. Now with cable (and satellite to an extent) being the dominant carrier of even broadcast channels, it's far easier to get direct and more accurate numbers from the cable companies.
It's Nielsen.
They still monitor only statistically preselected and voluntary viewers. That's the best they can do, since they can't get information of _all_ viewers. Just monitoring some viewers without any demographic information of them (for example, people having certain type of receiver allowing direct feedback) would distort the results.
