I and numerous others, seldom watch tv but have to have a licence. Why? so that the BBC can pay salaries etc that are not justified and also waste money on any stupid project that they wish.
Their public services are outdated and not needed, e.g. web sites. The same info is there in different places. We could quite happily live without their channels. There are numerous others.
All of the other channels make enough to keep going so why cant the BBC. Also what is the cost of collecting the licence money and policing it?
