The 1950s mark a significant change in the definition of the B movie. The transformation of the film industry due to court rulings that brought an end to many long-standing distribution practices as well as the challenge of television led to major changes in U.S. cinema at the exhibition level. These shifts signaled the eventual demise of the double feature that had defined much of the American moviegoing experience during Hollywood's Golden Age of the 1930s and 1940s. Even as the traditional bottom-of-the-bill second feature slowly disappeared, the term B movie was applied more broadly to the sort of inexpensive genre films that came out during the era, such as those produced to meet the demands of the burgeoning drive-in theater market. Fadeout of the classic B In 1948, a Supreme Court ruling in a federal antitrust suit against the leading Hollywood studios, the so-called Big Five, outlawed block booking and led to the divestiture of the majors' theater chains over the next few years. After barely inching forward in the 1930s, the average U.S. feature production cost had essentially doubled through the 1940s, reaching an average $1 million by the turn of the decade (the increase from 1940 to 1950 was 150 percent in simple terms, 93 percent after adjusting for inflation). With audiences draining away to television and other economic pressures forcing the studios to scale back production schedules, the Golden Age–style double feature began disappearing from American theaters. At the beginning of the 1950s, most U.S. movie houses still programmed double features at least part of the time. The major studios promoted the benefits of recycling, offering former headlining movies as second features in the place of traditional B films. Their longer running time appears to have both accommodated and hastened the progressive abandonment of the traditional "variety program" of newsreel/cartoon/short preceding the feature presentations at many theaters. With television airing many classic Westerns as well as producing its own original Western series, the cinematic market for B oaters in particular was drying up. The first prominent victim of the changing market was the Poverty Row studio Eagle-Lion, which released its last films in 1951. By 1953, the old Monogram brand had disappeared, the company having adopted the identity of its higher-end subsidiary, Allied Artists. The following year, Allied released Hollywood's last two B series Westerns, starring Wayne Morris: The Desperado in June and Two Guns and
