In the case of Jacobellis v. Ohio, decided in 1964, the U.S. Supreme Court addressed the issue of obscenity in film. The case arose when a theater manager, Katherine Jacobellis, was convicted for showing a French film that was deemed obscene by Ohio authorities. Jacobellis argued that the film was not obscene and that her conviction violated her First Amendment rights. The Supreme Court ultimately ruled in favor of Jacobellis, stating that the film did not meet the legal definition of obscenity. Justice Potter Stewart famously remarked that while he could not define obscenity, he knew it when he saw it, highlighting the subjective nature of obscenity laws.
