Interesting, in Croatia it's specifically a fee on owning any type of radio or tv receiver. Nowadays that applies to almost anything, from TVs and car radios to PCs and smartphones.
In Italy it doesn't apply to PCs and smartphones. It does apply to DVB-T dongles though.
It used to be a separate tax, now it's collected as part of the electric bill. You have to opt out explicitly instead of "opting in" by paying; this makes it much worse for people to evade the payment, since they would be making a false statement when opting out. So many people were evading the fee, that it has since been reduced by a third or so.
