Yeah, they've been around for years. It's illegal to have anything capable of 
receiving TV broadcasts in the UK without having a licence (about 160GBP/year, 
approx $140US). Doesn't matter if the equipment isn't switched on - if it's 
capable of receiving a signal then a licence is needed.

The vans can only detect a switched-on set, of course. I don't know if they 
can detect plasma screens or not - possibly, but not sure. Seem to recall that 
they use a directional antenna and just pick up on certain frequencies 
generated by all conventional sets.

Not many people watch TV on a computer screen though. Who'd want to? They're 
tiny in comparison to the average TV, plus the higher resolution of the 
computer display actually makes for a worse picture
