This is a question for the Daniweb members from the UK.
In North America we have seen a number of Americanized versions of British comedies. "Til Death Do Us Part" became "All in the Family". "Steptoe & Son" became "Sanford & Son", "Man About the House" became (the much inferior) "Three's Company". Here in Canada we also had access to original, unAmericanized British imports.
I'd like to know what North American sitcoms (if any) were ever adapted for British television, and what sitcoms aired unmodified? Which ones were the most popular?
