This is a cool set of maps of the popularity of 50 different TV shows across zip codes in the United States. But, what is the data and what exactly can it tell us? Here is the brief explanation:

When we looked at how many active Facebook users in a given ZIP code “liked” certain TV shows, we found that the 50 most-liked shows clustered into three groups with distinct geographic distributions. Together they reveal a national culture split among three regions: cities and their suburbs; rural areas; and what we’re calling the extended Black Belt — a swath that extends from the Mississippi River along the Eastern Seaboard up to Washington, but also including city centers and other places with large nonwhite populations.

Some quick thoughts:

1. Can we assume that Facebook likes are an accurate measure? How many people are represented per zip code? Who tends to report their TV show preferences on Facebook? Why not use Nielsen data which likely has a much smaller sample but could be considered more reliable and valid?
2. How exactly does television watching influence everyday beliefs and actions? Or, does it work the other way: people have certain beliefs and behaviors and they watch what confirms what they already like? Sociologists and others that study the effects of television don’t always have data on the direct connections between viewing and other parts of life. (I’m not suggesting television has no influence. Given that the average American still watches several hours a day, it is still a powerful medium even with the rise of
3. The opening to the article both suggests TV viewing and the related cultures fall along an urban/rural divide but then also split across three groups. The maps display three main groups – metro areas, rural areas, and areas with higher concentrations of African Americans. I would want to know more about two areas. First, political data – and this article wants to make the link between TV watching and the 2016 election – suggests the final divide is really in the suburbs between areas further out from the big city and those closer. Can we get finer grained data between exurbs and inner-ring suburbs? Second, does this mean that Latinos and Asian Americans aren’t differentiated enough to be their own TV watching cultures?
4. The introduction to this article also repeats a common line among those that study television:

In the 1960s and ’70s, even if you didn’t watch a show, you at least probably would have heard of it. Now television, once the great unifier, amplifies our divisions.

We certainly are way into the cable era of television (and probably beyond with all of the options now available through the Internet and streaming) but could we argue instead that the earlier era of fewer channels and viewing options simply papered over differences? As numerous historians and other scholars have argued, the 1950s might have appeared to be a golden era but most of the benefits went to white, middle class, suburban families.

In other words, I would be hesitant to state that these TV patterns are strong evidence of three clearly different cultures in the United States. Could these television viewing patterns fit in with other cultural tastes differentiating various groups based on class and race and ethnicity? Yes, though I’d much rather see serious academic work on this developing Bourdieu’s ideas and encompassing all sorts of consumption items treasured by Americans (homes, vehicles, sports fandom, making those hard choices like Coke and Pepsi or McDonald’s and Burger King or Walmart and Target). Also, limiting ourselves to geography may not work as well – this approach has been tried by many including in books like The Big Sort or Our Patchwork Nation – as it did in the past.
