A B-Picture (or: B-movie) is a low-budget commercial motion picture that is neither neccessarily an arthouse nor pornographic film. In its original usage, during the Golden Age of Hollywood, the term more precisely identified a film intended for distribution as the less-publicized, bottom half of the notorious double feature. As the popularity of double features largely ceased by the end of the 1950s, the term B-movie continued to be used in the broader sense, as it is known to us today. In its post–Golden Age usage, there is ambiguity on both sides of the definition: on the one hand, many B movies display a high degree of craft and aesthetic ingenuity; on the other, the primary interest of many inexpensive exploitation films is crude and vulgar. In few cases, one may not neccessarily rule out the other.
