Career
Brian Green co-founded ComedySportz in Milwaukee, Wisconsin, in 1984 as one of four founding performers and organizers alongside Dick Chudnow, Karen Kolberg, and Bob Orvis. The format they developed, initially called TheaterSportz in reference to Keith Johnstone's Theatresports tradition, structured improvised comedy as a competitive event in which two teams perform improv games and scenes judged in real time by the audience through referee calls and crowd participation. The format was officially renamed ComedySportz in 1987.
The inaugural ComedySportz performance took place in September 1984 at Kalt's Restaurant on Oakland Avenue in Milwaukee, Wisconsin. Green was among the original performing group that established the show's conventions and developed the competitive improv format in its early months. The first affiliate franchise opened in Madison, Wisconsin, in 1985. The Comedy League of America, the organization's national competitive structure, launched its first national tournament in 1988.
Green has maintained a continuous performing presence with ComedySportz Milwaukee from its founding. He is described by Milwaukee press as a veteran of both improv and stand-up comedy. The Shepherd Express, in a 2016 article on the Milwaukee comedy scene, listed him alongside other figures as a veteran presence in the city's comedy community. He has continued to perform at ComedySportz Milwaukee, where the organization operates at 420 S. 1st Street in Milwaukee.
Green participated in a 2015 conversation with Milwaukee Magazine in which he and Anton Johnson discussed whether Milwaukee's comedy scene is racially segregated, reflecting his public role as a senior figure in the Milwaukee comedy community with a perspective on the city's comedy demographics.
ComedySportz Milwaukee trained and developed the comedy writer and television producer Dan Harmon, creator of NBC's Community and co-creator of Adult Swim's Rick and Morty, who has credited the Milwaukee organization's training programs with skills foundational to his writing career. Green's presence as an original performer and the continuity of ComedySportz Milwaukee through its founding decades contributed to the institutional context in which this training occurred.
Historical Context
Green's co-founding of ComedySportz in 1984 placed him among the small group of individuals who established one of American improv's earliest franchise formats, preceding the national expansion of iO, UCB, and Second City training programs by a decade or more. The competitive format that Green and his co-founders developed in Milwaukee created a production model oriented toward audience participation and entertainment accessibility that distinguished ComedySportz from both the Harold-based long-form tradition developing at iO Chicago and the revue format of Second City. Where the Harold asked audiences to provide a single word suggestion and then watch a complex long-form show develop, ComedySportz made the audience an active participant through referee calls, audience scoring, and competitive team structure, lowering the barrier to comprehension and engagement.
The ComedySportz format's expansion to franchise affiliates beginning with Madison, Wisconsin, in 1985, and its establishment of the Comedy League of America national tournament in 1988, produced one of the earliest systematized improv franchise networks in American comedy, with a competitive infrastructure that gave affiliate cities both a production format and a national competitive community. Green's presence as an original performer through the founding and early expansion decades placed him at the institutional center of this development.
The connection between ComedySportz Milwaukee's training programs and the subsequent career of Dan Harmon, whose Community and Rick and Morty have been among the most analytically discussed American television comedies of the 2000s and 2010s, reflects the degree to which a regional improv institution can produce alumni whose careers extend well beyond the local comedy community that sustained the organization during its founding decades.
Legacy
Green's co-founding of ComedySportz in 1984 contributed to the creation of a competitive improv format that expanded to franchise affiliates across the United States and internationally, becoming one of the most widely distributed competitive improv brands in American comedy. His continuous performing presence with ComedySportz Milwaukee across more than four decades represents an unusual degree of institutional continuity, sustaining the format's home presence through the entire arc of the franchise's national expansion and multiple changes in the broader American comedy landscape.
ComedySportz Milwaukee's alumni network, which includes Dan Harmon among others, reflects the training function that the Milwaukee organization performed for the local and regional comedy community across its founding decades. Green's role as an original performer and his sustained presence through this period placed him within the institutional environment that produced these outcomes and that kept ComedySportz Milwaukee visible as the flagship location of a nationally operating format.
His public engagement with questions about the Milwaukee comedy scene's demographics, documented in his Milwaukee Magazine conversation with Anton Johnson in 2015, reflects the perspective of a practitioner with more than three decades of visibility in a single regional comedy community, one who has observed the city's comedy scene through the full arc of American improv's national expansion from the format's founding years to the present.
