Hamblin defied conventions of theatre as high culture by booking productions that appealed to working-class patrons and by advertising them extensively according to Gilfert's model. Animal acts, blackface minstrel shows, and melodrama enjoyed the most frequent billings, and hybrid forms, such as melodramas about dogs saving their human masters, became unprecedented successes. Spectacular productions with advanced visual effects, including water and fire, featured prominently. Hamblin also innovated by using gas lighting in lieu of candles and kerosene lamps. The Bowery Theatre earned the nickname "The Slaughterhouse" for its low-class offerings, and terms like "Bowery melodrama" and "Bowery actors" were coined to characterize the new type of theatre.
