It's a ridiculous cliché to say that British telly is the best in the world, but there's also some truth in it. Try watching US telly sometime - yes, there are good programmes on (after all, many of them are shown on British telly too) but the amount of utter irredeemable tripe is enormous and far outweighs the good stuff (at least on terrestrial). One very good reason that there is no licence fee in the States is that nothing being put out on the terrestrial networks is worth it.
We have a TV in order to watch Star Trek. That's about it.
