What? "200k people prosecuted" for not paying a TV license? i find this really hard to believe what evidence can you really use that someone is watching live tv. If someone watches it via computer and they tv company work with the broadband provider to establish this the argument could always be someone is bootlegging your WIFI. They could take your computer to check but seems costly procedure for the £1k fine.
Having a TV in your house doesnt hold up as proof either in court. Total scam this TV license thing.
