In the UK, we pay a TV licence. There are detector vans which track down

thing' because it interferes with things. With modern sets, it's
probably easier to look for the rubbish from the switch-mode power
supplies (which is often worse when the set is in standby).

It used to be said that the TV manufacturers were actually willing to
improve their designs in order to reduce the radiation, but were
pressured not to do so! I'm not sure how true any of this is. I've a
sneaky feeling that costs again come into it somewhere.

Which reminded me of the "Cat Detector Van" sketch. Monty Python was so
good.
