I think it depends on where nnutter lives, and it also depends on his social circle. Since nearly none of my friends have TVs, I can go months without seeing an ad. (I myself do have a TV, but I only watch public broadcast channels that do not have ads except for their own programming.)
I can believe it. I haven't owned a TV in many years, and while I do see an ad or two relatively regularly (my parents own a TV), even when I visit them I often never see it on.
Outside of visiting them, I can't even think of any situations where I'd encounter one. We've got TVs in work but they only show static screens with schedules and notifications. No channels. None of my friends own one and I do actively avoid sports bars.
I'm probably in a minority but I don't think I'm extremely unusual. Definitely a fast growing minority at least.
