The figure probably includes a lot of old folks in nursing homes who are wheeled in front of the tv set and have absolutely no idea what they are watching. I remember when my beloved mom was in one, and they moved her to the second floor (always a bad sign); I walked in one afternoon and the attendants had about 20 of the residents watching the movie Psycho with the volume turned up as high as you could get it. On second thought, I think they would rather watch the crazed Anthony Perkins than the crazed Adam Schiff or Fatman Nadler.
They are probably counting every last person who walking into an airline terminal and glanced at one of the ubiquitous CNN television screens.
