The US, with very few exceptions, does not adopt British TV. We insist on adapting British TV; i.e., changing it. The worst example was “adapting” Fawlty Towers by making Bea Arthur play John Cleese AND Sybil????
The Brits get to see almost all US shows at the same time as US viewers. We in the US-with the exception of PBS and toavery small extent, BBC America-never get to see the vast majority of British shows. And why the hell does BBC America show “chef” Ramsay again and again????
