Tom of Finland's Untitled (c. 1986). Pornography was, then, a category of material created, invented, and produced as a means to regulate and target the moral behavior of certain populations. The seizure of and legislation against so-called pornographic work provided a means of increasing the surveillance of working-class people and all women. For pornography to exist, "a public which might be corrupted by obscene publications had to exist." —Michel Foucault, History of Sexuality.
