It does make me wonder how many people (households) do pay for a TV licence.Where did you hear this?
Agreed. If you ask kids these days about this topic they are shocked a license is needed to view live "TV" but do not need a license to view any content that is live but not deemed to be "on TV"; when you ask if they think they will buy a license when they are older they generally say no because they watch video clips on an 'on demand' basis when they want.
Back in 1988 when I bought my house I did not have a TV and I never got reminders. I was hardly ever in and never got round to getting a TV. In about 1992 I thought I better have a TV in case of visitors I also had more money four years into a mortgage and more time to watch TV (less overtime and commuting time I think). Last ten years I have been sharing with my partner at her house so I stopped getting a licence for a house I hardly use and have scrapped the TV (old tube monster). But since then, every two years, I have been pestered incessantly if I do not get round to going through their hooped requests quick enough !. It is quite threatening them saying they will break down the door !.
