Why are professors teaching courses on The Wire?

From Drake Bennett at Slate Magazine, Why so many colleges are teaching The Wire. An excerpt:

Academics, on the other hand, can’t seem to get enough of The Wire. Barely two years after the show’s final episode aired—and with Simon’s new show, Treme, premiering next month on HBO—there have already been academic conferences, essay anthologies, and special issues of journals dedicated to the series. Not content to write about it and discuss it among themselves, academics are starting to teach it, as well. Professors at Harvard, U.C.—Berkeley, Duke, and Middlebury are now offering courses on the show.

Interestingly, the classes aren’t just in film studies or media studies departments; they’re turning up in social science disciplines as well, places where the preferred method of inquiry is the field study or the survey, not the HBO series, even one that is routinely called the best television show ever. Some sociologists and social anthropologists, it turns out, believe The Wire has something to teach their students about poverty, class, bureaucracy, and the social ramifications of economic change.
