Ye gods!
THE LICENCE IS NOT FOR WATCHING BBC!
IT IS FOR WATCHING ANY LIVE TV BROADCAST.
But the BBC have collected the fee and, for doing so, have always been gifted it back, these days they pay it into a government fund and the DCMS votes it back to them! It pay for the wider range of stuff it does. It used to pay for the broadcast infrastructure, masts etc, now it contributes:
In addition to funding BBC programmes and services, a proportion of the licence fee contributes to the costs of rolling out broadband to the UK population and funding Welsh Language TV channel S4C and local TV channels.
Object to paying the licence by all means, but know what it is you are objecting to... that is having to pay if you use TV receiving equipment to watch or record television programmes as they’re being shown on TV. ‘TV receiving equipment’ means any equipment which is used to watch or record television programmes as they're being shown on TV. This includes a TV, computer, mobile phone, games console, digital box, DVD/VHS recorder or any other device.
