To a certain extent yes. It seems to be the way that the Western world is going, so don't feel too unique. Every country has some sort of stereotype attached to it's culture, and for England it was about being prim and proper - something which still seems to be propagated to a certain extent. Now when they go to write a guide book they're just realizing that for the most part a lot of modern society is very similar.
(That doesn't mean I don't still have a little soft spot in my heart for the UK).
