In the UK, you have to pay a yearly fee to watch live TV. It goes to the BBC, which is why there are no adverts on any of their channels. But you have to have one in order to watch anything on TV. Note how I said live TV. You can watch catch up TV without needing a TV license. This is how Chris saves money by not needing to buy a TV license.

But, weirdly, you need one in order to use game consoles. Strange, I know, but hey.
