all possible things that are considered as TV receiver - any smart phone, tablet, PC including all *book, and of course all possible TVs. "reasoning" - you can still watch stuff online.

and there might be sub-fee for just radio receiving, in case you really don't possess any video-displaying device. And again any of those devices (over internet for example) apply.

I don't pay them where I live currently (Switzerland) - the private company which has government mandate to extract fees (Billag) has questionable legality over incurring any fees (which can go up to 5000 CHF =~ 5000 USD), and they need to physically inspect your apartment before any action. Of course there is no force in universe that would make me let them in. Reason - I haven't watched any broadcast TV station (or any other) for last 5 years. Plus we pay for TV channels to internet provider quite hefty sum already (part of the package, unused). If it's not illegal, it's immoral to extract those fees.
