American refers to the people and culture of the United States of America. By comparison, the U.S. of A. is still a relatively young country whose history dates back to the colonial era of the 17th century and on through to the 18th century, when they declared their independence from England, threw all their tea into the harbor, blamed it on the Indians, and then had a big ol' war to hash everything out. In the end, the Brits shook their heads and said, "Ahhh... let 'em have it", and that was that. Two centuries and a couple of decades later, Americans honor the sacrifices of the founding father by cracking off fireworks, drinking beer, eating lots of barbeque and deep frying everything they can squeeze into a pot of oil. They also pioneered the concept of reality television. The less said about that the better.
