Just do it like the UK do, they have it down pat.
They don't even bother with monitors, especially when it comes to paying TV license fee's, yes my brothers and sisters TV license fee's.
If you own a Television in the UK you MUST pay £135.50 per year for the privilege.
So what you may think, here is more, if you own a vcr, dvdr,or a mobile/cell phone but no TV, you still pay, yes thats right, you still pay.
By the way, you may be thinking so who will know? lmao, they know, they know everything, rock on.
