Cultures create institutions that reflect their values and interests. But it works both ways. Institutions create cultures, as well.
For example, the automobile industry was created by American ingenuity, entrepreneurship, hard work and enough natural resources to build millions of cars. At the same time, few inventions have done more to create modern America. The automobile has reinforced our distaste for practical mass transportation, as well as shaped the looks of our cities and towns. The automobile has even had a significant impact on the composition of the air that we breathe and our climate.
In fact, it's impossible to imagine modern America without the automobile.
Or without professional football. And America's relationship with the sport is similarly interesting and complicated.
America was a fitting location for the invention of football. All of the sports that we really like involve two teams trying to reach goals at opposite ends of fields or courts - baseball is the prominent exception. But football is the only one - except for its less-popular, non-American progenitor, rugby - that depends on violent force, only mildly restrained by rules, to reach its goal.
Other popular sports involve forays toward the goal in the opponents' territory, alternating with orderly, fluid retreats to defend one's own goal. Football is built around the principle of conquering and controlling territory - field position - in a way that progressively brings the goal into reach.
In short, football serves as an apt parable for the creation of our nation, which depended on the acquisition and control of territory by force. We're not the first nation to be created in this way, but this comparatively recent narrative is central to our history. I'm not saying that it was a bad thing. I'm just saying.
For decades football was a pleasant way to spend a crisp fall afternoon, but technology spawned the pervasive eminence of the modern game. Air travel allowed professional football's expansion to more cities, and the NFL appears to have its sights on international expansion.
