Re: Telly Tax exit stage right!!
Indeed, but that's actually the biggest philosophical change. Previously the licence was for the reception of broadcasts (originally radio, then TV); it was never for owning the equipment. Also, the licence fee does *not* go to the BBC; it goes to central government funds who every three years agree a grant to the BBC which, by coincidence, closely tracks the licence revenue.
Charging to watch catchup - which has been a huge hole in the system - is effectively charging per device (or at least, per household).
