America?

So a few nights ago, as I was trying to fall asleep, I started thinking (maybe because of the upcoming 4th of July?): what if we didn't win the revolutionary war? How would America be different? Would we still be called America? Would we be more like Canada where we have a  quintessentially British style parliament & have the queen on our money? How long would we have been a British commonwealth? Or would we have still asserted our independence just at a later date? If we were not called the United States of America, what would we have been called (South Canada maybe? lol)? And what would South America be called? Ah, the things that make you go "hmmm"...
