People of a certain age like me will remember the TV detector vans, that would prowl the streets at night looking for unlicensed tellys in use.
Or so we were told. In fact the vans contained no electrical equipment, because the supposed technology didn’t exist. All they had was a list of houses that didn’t have a tv license and they would park outside in the hope of spotting a blueish glow through the curtains, which is why they only operated at night.
