It is not about possession of devices (television) at all. I could have a thousand TV sets connected to a thousand aerials/dishes with a thousand set-top boxes and a thousand PV recorders along with a whole bundle of computers, phones, tablets & consoles etc all capable of receiving and/recording live tv and iPlayer in my house.It's going nowhere, it was always about possession of a device (television) capable of displaying broadcast channels and content. Whether you watch the BBC or not is neither here nor there.
If I watch or record live tv on any channel whatsoever from any broadcaster whatsoever or watch or record any iPlayer content on just one of them I need a licence. If I watch or record live tv/iPlayer on none of them, I do not need a licence.
A licence is not needed to own, have or operate any TV receiving device. The licence simply permits the viewing/recording of live tv or any iPlayer content at the licensed address.
Clearly, possession of kit may tip the balance of probabilities in favour of the prosecutor but the reality is of is that without a confession or without being caught viewing/recording live tv/iPlayer red handed, there is no prosecution.
Radio licences were abolished in 1971.Technically you needed (maybe still need, I have not checked to see if this has changed recently) a license for a public band radio receiver but they just didn't/don't bother with that bit.
Radio Licences were required from around 1920 but included TV until 1946 when TV licences were introduced. Thereafter, TV licences included the radio but for those who only ever listened to a radio, a radio specific licence was needed.
Oddly, No licence is needed to listen to radio channels on BBC iPlayer.
