You raise a very interesting point. Just because a lot of American companies draw a large amount of income from abroad does not make them respect the market or adjust the product to that market. IN fact, US imperialist policy (and that is simply what it is, don't take me for a rebel commie, but a country that has been at offensive war for most of it's history cannot be named anything but an imperialist) has insured that other countries are force fed American products, right after we liberize them, as in liberate for immediate colonisation.
