Interesting. I didn’t know using the website counted as watching TV. Is that really included in the law?if you lived here they'd be after you for £150+ per annum; using the website counts like watching TV, so they'd (subcontracted out to Capita?) come down on Shad like a ton of bricks. Listening to the radio bizarrely doesn't count - for now.
I do have some experience. They used to go around with vans picking up signals. Many decades ago I remember you didn’t have to have a TV license if you had a TV but didn’t use it to pick up broadcast signal or some such. There was a court case about that I vaguely remember.
Edited to add:
Golly. You are absolutely right. Since 1991. So there must have been an updating to account for streaming services. I think my personal experience may be older than that. Or more recently but before it all got serious.
