Cinematic exhibition of the B movie, defined as a relatively low-cost genre film, has declined substantially from the early 1980s to the present. Spurred by the historic success of several big-budget movies with B-style themes beginning in the mid-1970s, the major Hollywood studios moved progressively into the production of A-grade films in genres that had long been low-budget territory. With the majors also adopting exploitation-derived methods of booking and marketing, B movies began to be squeezed out of the commercial arena. The advent of digital cinema in the new millennium appeared to open up new opportunities for the distribution of inexpensive genre movies.

The B movie loses its place: 1980s

Most of the B-movie production houses founded during the exploitation era collapsed or were subsumed by larger companies as the field's financial situation changed in the early 1980s. Even a comparatively cheap, efficiently made genre picture intended for theatrical release began to cost millions of dollars, as the major movie studios steadily moved into the production of expensive genre movies, raising audience expectations for spectacular action sequences and realistic special effects. Intimations of the trend were evident as early as Airport (1970) and especially in the mega-schlock of The Poseidon Adventure (1972), Earthquake (1973), and The Towering Inferno (1974). Their disaster plots and dialogue were B-grade at best; from an industry perspective, however, these were pictures firmly rooted in the tradition of star-stuffed extravaganzas like The Ten Commandments (1956) and Around the World in Eighty Days (1956). The Exorcist (1973) and, though not effects-driven, George Lucas's American Graffiti (1973) were the first serious steps in Hollywood's transformation into an industry built around high-budget B-themed movies. But the tidal shift in the majors' focus owed largely to the enormous success of three films: Steven Spielberg's creature feature Jaws (1975) and Lucas's space opera Star Wars (1977) had each, in turn, become the highest-grossing film in motion picture history. Superman, released in December 1978, had proved that a studio could spend $55 million on a movie about a children's comic book character and make a very handsome profit. Not an all-time record-breaker like Jaws and Star Wars, it was merely the biggest box-office hit of 1979. Blockbuster fantasy spectacles like the original, 1933 King Kong had once been exceptional; in the new Hollywood, increasingly under the sway of multi-industrial conglomerates, they would rule.

It had taken a decade and half, from 1961 to 1976, for the production cost of the average Hollywood feature to double from $2 million to $4 million—actually a decline if adjusted for inflation. In just four years it more than doubled again, hitting $8.5 million in 1980 (a constant-dollar increase of about 25 percent). Even as the U.S. inflation rate eased, the average expense of moviemaking would continue to soar. With the majors now routinely saturation booking in over a thousand theaters, it was becoming increasingly difficult for smaller outfits to secure the exhibition commitments needed to turn a profit. Revival houses were now the almost-exclusive preserve of the double feature. One of the first leading casualties of the new economic regime was venerable B studio Allied Artists, which declared bankruptcy in April 1979. In the late 1970s, American International Pictures (AIP) had moved into the production of relatively expensive comedies and genre films like the very successful Amityville Horror and the disastrous, $20 million Meteor in 1979. That same year, the studio was sold off to Filmways, a company with a history in TV production, and was dissolved as a moviemaking concern by the end of 1980. Capitalizing on the popularity of Hercules, in 1960 Roger Corman had made Atlas for a total of $75,000. In 1982, Universal released a movie in the same tradition: fantasy plus muscles. The lead role was to be played by an Austrian-born actor with a great reputation as a bodybuilder but entirely unproven as a major film star. Adjusting for inflation, the cost of Atlas was about $400,000 in 1982 dollars. Production cost on Conan the Barbarian was an estimated $20 million. Hercules had opened in 600 theaters, an astonishing figure at the time. Conan opened in 1,395, making it one of more than twenty movies that year to open at over 900 theaters.
