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.
