Poverty Row was a slang term used in Hollywood from the late 1920s through the mid-1950s to refer to a variety of small (and mostly short-lived) B movie studios. While many of them were on (or near) today's Gower Street in Hollywood, the term did not necessarily refer to any specific physical location, but was rather a figurative catch-all for low-budget films produced by these lesser-tier studios.
The films of Poverty Row, many of them Westerns (including series like Billy The Kid, starring Buster Crabbe from PRC) or comedy/adventure series such as those featuring the Bowery Boys (Monogram Pictures) and detectives such as The Shadow, were generally characterized by low budgets, casts made up of lower ranked stars or unknowns, and overall production values that unintentionally betrayed the haste and economy with which they were made.
While some Poverty Row studios came and quickly went after a few releases, others operated on more or less the same terms as—if vastly different scales from—major film studios such as Metro-Goldwyn-Mayer, Warner Bros., and Paramount Pictures.
The most successful and longest-lived of such lower-tier companies maintained permanent lots (and many standing sets that dedicated moviegoers could frequently recognize from movie to movie), had both cast and crew on long-term contract, and had a more varied output than smaller firms.
The smallest studios, including Tiffany Pictures, Sam Katzman's Victory, Mascot and Chesterfield often packaged and released films from independent producers, British "quota quickie" films, or borderline exploitation films such as Hitler, Beast of Berlin to supplement their own limited production capacity. Sometimes the same producers would start a new studio when the old one failed, such as Harry S. Webb and Bernard B. Ray's Reliable Pictures and Metropolitan Pictures.
