WTF only 3000? Where are these 3000 based? Surely we have the technology to have every single household counted? Or at least in 2014 when every single TV is running digitally we surely would have that sort of technology

Each tv would have to be either wired to the Internet, a fixed phone line, or a 3G chip in it to send the information back.
