Yup - British music is popular (Leona Lewis), as are British films (Hot Fuzz and watever Hugh Grant is up to), British literature (Shakespeare, Harry Potter), British Cuisine (English Muffins, and all food they inherited such as Fish and Chips, Sunday Roast etc), and British based tv shows (The Office, Britain's got talent).
Fairly popular I would say. Not surprising seeing as Britain is a cultural superpower, along with the USA itself, and Japan.
