How did comedy teams in vaudeville differ from solo stand-up performers?

In the context of early 20th-century vaudeville, comedy was primarily defined by the interaction between performers rather than direct engagement with the audience.

Comedy teams were a staple of the vaudeville bill, relying on packaged routines where the performers spoke to one another rather than to the crowd. In contrast, the emerging style of solo stand-up—which would later become the modern standard—was characterized by a direct, off-the-cuff connection with the audience.1

Early solo performers, such as Frank Fay, began honing this style while serving as emcees in vaudeville houses. This approach shifted away from the generic, interchangeable gags used by vaudeville teams toward a more personalized, topical monologue style. This evolution was further developed by comedians in the Borscht Belt and popularized by figures like Bob Hope, who utilized teams of writers to create fresh, news-driven material that departed from the endlessly repeated routines common to the vaudeville era.1
