This highlights some oddities of the UK TV licensing system. I can listen to BBC radio all day every day; I can use the BBC websites all day every day; I can watch BBC TV programmes on their iPlayer service (so long as the programmes are "catch-up" and not streamed live) and I do not need a licence.
I only need a licence if I watch tv broadcast live. Everything is defined in law; the devices used to receive (which include smart phones and computers) and the signals (which weirdly include for example French telly received via satellite). A person could hate the BBC and all its output and never watch it but still need to pay the licence fee.
Personally, I welcome the BBC but the enforcement of the licence has been sub-optimal in the past.
