What has the United States ever done for culture?

Recently I have had to play the “let’s name everything that sucks about the United States” game over and over again. The most recent edition was, “What has the United States ever contributed to culture?”

I was thinking that the reason there are few “American” cultural contributions may be because America has so many different subcultures—New England, California, the Pacific Northwest, the South, the Southwest, and the mid-west, just to name a few.

So, with this in mind, can you help provide me with some ammunition for the next round of this game? What has your region, or America as a whole, contributed to culture? So far, my starter list is:

peanut butter
mint juleps
Woody Allen movies
