Also, alledgely, using scanners to catch cheaters. Though I got a visit from a man checking for unlicensed TV sets once and he didn't have a scanner, just a long list of people that didn't have a TV license.

There was also the funny scare tactics commercials where they said you would get a snail on the eye if you didn't pay.

I bought a new TV and got a phone call from Radiotjänst a couple of weeks later, asking where they should send the bill for the TV license. Busted!

Now that the fee is discontinued, and it comes out of tax money instead, I sure don't miss getting those invoices.

The electronics stores had a reporting duty as I remember.

Yeah, it was some law iirc. Regarding being busted, i was zapping one day when the bell rang so i opened the door to the inspector with the remote in my hand and the TV blaring, THAT'D i call getting busted :D

Apparently, they actually had scanners, but never used them

Worth noting that the license fee is now paid as part of the regular tax payment. So the tax authority manages the collection, as opposed to previously when it was a separate agency.
