In 1982, Ellen Holbrook, a former student at Second City in Chicago and a producer of the Chicago Improv Olympic, moved to Boston with the idea to found an improvisational comedy troupe similar to Second City. Holbrook had the encouragement of former members of The Proposition, an earlier improv-comedy troupe, and Director David Shepherd, the founder of the Compass Players and the Improv Olympic. In the beginning, she assembled and trained several loosely knit bands of improvisers into teams that competed in the Boston "Improv Olympic" at Reilly's Beef and Pub near Government Center. Holbrook also arranged for David Shepherd and Second City's Michael Gellman to come to Boston to teach improv workshops to local performers. In 1983, Holbrook, along with Nicholas Emanuel and Katy Bolger, co-founded ImprovBoston, as the organization evolved. With their contacts, the group moved to Satch's near Copley Square, owned by former Boston CelticSatch Sanders. In 1984, ImprovBoston officially became a not-for-profit corporation and moved to Ryles Jazz Club in Cambridge at Inman Square, where they remained for several years. Show formats varied but often included several improv games based on audience suggestions, set sketches based on improvs from past shows, musical improvs and song parodies. ImprovBoston troupe members often took turns directing shows, but other ImprovBoston directors during this time included David Thibodeaux, Jack O'Connor, Leslie Curtin and Brad Jones.
In 1993, under the leadership of Artistic Director Nancy Howland Walker, ImprovBoston acquired a lease to the Back Alley Theater in Inman Square - ImprovBoston's first dedicated theatre space. The ImprovBoston Mainstage cast performed late night weekend shows for several years, eventually expanding to prime time slots. Walker was just as instrumental in obtaining the New England franchise of Theatersports, which eventually became a regular Thursday night show at the theater. During Walker's tenure, the cast grew from five to well over 20 members. Larry Pizza became Artistic Director in 1995 and, in 1997, the artistic leadership again transferred, this time to Ron Jones, a former cast member from the early 1990s. It was under Jones' leadership that the theater began to extend its reach to further aspects of improvisation, creating new formats and shows beyond the traditional shortform game format the theater used for their Friday and Saturday night shows.
Early 2000s and The Move (2000-2008)
In 2000, former cast member Will Luera returned to ImprovBoston as the new Artistic Director, bringing with him several show concepts and forms he had established under the banner of Bluescreen Productions. This merger saw a third cast added to the ImprovBoston line-up, as ImprovBoston was granted the rights to Keith Johnstone's Micetro format. The theater's cast was again expanded in 2005 when the ensemble "Wrong Kind of Funny" was brought into what eventually formed IB's Family Show. In February 2008, ImprovBoston moved to a new venue in Cambridge's Central Square, where it continues to operate today. Luera was responsible for the theater's most aggressive expansion, with several new shows, concepts, and formats established; and for keeping the theater doors open on five nights each week. The Hump on Wednesday nights, The Great and Secret Comedy Show late Thursdays, bi-monthly Showcase Shows in the early Friday night slot, and the Sgt. Culpepper Improvisational Jamboree on Sunday nights. ImprovBoston also established new annual productions including GoreFest, The ImprovBoston Holiday Spectacular, the Comedy Beanpot. In the past, ImprovBoston has also hosted The, Geekweek, Comedy Beanpot In 2010, the theater created an audio department with the intention of producing weekly free podcasts among other audio-only endeavors under the banner of "ImprovBoston Radio". This resulted in the flagship, and also Fireside Improv, a more instruction-oriented look at the comedic form with a panel of improv pupil, professor and philosopher.
Since 2012
The current management staff is in a transition period led by Leslie Walstrom, Elyse Schuerman, Will Luera and Emily DiPietro.
