And even if some brands would not be exclusively sold in the us, but a handfull of countries elsewhere, that is a long way from worldwide sales (something being sold on the opposite side of the world does not equate to worldwide, eventhough it is spread out wide then)
mountain dew is one you hear about through popculture and dr pepper (though we do have the latter here not, sure that is the case for every country)
Just because you've seen something outside of the usa does not mean it's everywhere. And your examples are rather crazy and over the top. And I don't see why you are using Coca cola as an an example noone said that that wasn't a worldwide thing. You are claiming that if something is sold in the US and in Cuba, or lets pick a place further away, Brunei it is a worldwide phenomenon. Sorry man 2 countries definitely does not equate to worldwide. Many, yes and that was exactly what I was saying. Saying 49 states is not nationwide is indeed daft, just as daft as saying in 2 states is everywhere in the US..
as for your 2nd reply saying indeed the bottom 4 are less known globally, so why the whole reply in the first place.
And seriously not need for the downputting.
