Some time ago, in a PhD seminar on cultural markets at Columbia University, a group of students decided to conduct a rapid investigation of New York’s videostores. We selected five different areas—the Upper West Side (intellectual petty bourgeoisie), the Upper East Side (wealthy Manhattan), the East Village (bohème), the Bronx (focusing on a Puertorican area), and Harlem (African-Americans)—and for each of them we analysed the composition of a half-dozen videostores that seemed reasonably representative. That’s not the way to do statistical research, a sociologist friend told me, and he is certainly right. But I still hope our findings may be of some interest.

Unlike Benedetto Croce, videostore owners have a firm belief in the reality of literary genres. As soon as you enter, you realize that each and every tape is ‘labeled’ in one way or the other. ‘People usually don’t want a movie by X or Y’, I was told; ‘but a comedy, or a musical: they look for this or that genre.’ Truth be told, these genres hardly form a flawless system; although some are genuine genre definitions (‘Thrillers’, ‘Comedies’, ‘Sci-Fi’), others don’t point to the film, but to the audience (‘Children’), or the place of production (‘Foreign Films’), or some vague realm of the spirit (‘Classics’). But this mess does not stop a literary critic, with the novel it’s not better, and at least all videostores use the same terms, which makes a comparative analysis possible.

So, we counted how many comedies, foreign films, etc., were present in the various stores, and figured out their relative weight. We wanted to look at lending records, but privacy norms forbid it, so we had to turn from actual choices to potential ones—what videostores have to offer. And this is what we found.

First of all, a gap between the videostores of Harlem and the Bronx, and the other three areas. It may be summarized thus: in the Bronx and in Harlem, the presence of the genres ‘Action/Adventure’ and (to a lesser extent) ‘Horror/Sci-Fi’ is roughly three times higher than elsewhere, and adds up to 50 per cent of the total.

As the section ‘Action/Adventure’ includes (at its best) Rambo, Rocky, Batman, Indiana Jones, Top Gun, Terminator, Jurassic Park, Natural Born Killers and so on, we quickly found ourselves discussing the issue of ‘violence’ in these films—which is the sort of thing that looks perfectly obvious, until you actually start thinking about it. Because, after all, how is one supposed to identify violence in a movie: by the litres of blood? (But that isn’t blood, it’s tomato sauce.) By the length of sharks’ teeth? (But white-gloved Mackie Messer is worse than any shark.)
