Actually, if you were to watch British commercials, and compare them to American commercials, they're almost alien to one another. Why? Because the people are different, commercials are designed to attract a majority populace.
Now obviously, the type of advertisement reflects what type of people they are targetting. It works, otherwise they wouldn't spend millions on it.
American adverts, in my experience, are in your face, energetic, sales driven enthusiasts. British adverts are much more subtle, quieter, and complicated, and at times more rude. Infact, sometimes, they insult their own product and even the prospective customer. This is clever because, when you meet a stranger, they will be polte, respectful, even if they dont like you.
But a very good friend, would easily be able to critisize you, or be rude infront of you. So the British/European type adverts, are designed in a way to make the company more 'friendlier' and customer orientated, and not afraid to critisise, because critisism is usually a sign of honesty and integrity.
American adverts would fail miserably in Britain, because when we see them, we laugh out at the absurdity of their selling techniques.
Likewise, British adverts would more or less, confuse or alienate the Americans.
I'm not generalising, but i say that these things would maybe apply to at least half the population of both countries.
The reason we know quite a bit about American entertainment is because here in Britain, MANY of our programmes, are eventually converted into an American equivalent. Like Big Brother, Who Wants to be a Millionaire, even obscure stuff like Ali G, and Trigger Happy Tv, and it's remarkable the alterations they make to the programmes to attract a wider audience.
Anyway...American 'Imperialism' is way more commercial/cultural than anything else. Unfortunately, it is constant bombardment, and it does indoctrinate to a great extent, so much so, that when foreigners in their home lands, learn the english language, even from a foreign teacher, they speak it in an American accent. And NOT the PROPER SCOTTISH accent!!!
(yep im scottish) and we pronounce our r's like they should be
its alRIGHT not ALWITE! GRRRRRRR
