IO Theater is a comedy venue and school that teaches and performs improvisational comedy
IO Theater (originally called ImprovOlympic) is a physical space where improv performers take the stage and where people can learn improv in classes. It is not a bank product or a financial service — it is a live entertainment venue. If you arrived here from the improv category, you may have been looking for information about how improv works as a performance art, or what happens when you attend or study at a place like IO.
IO Theater operates as both a performance space and a training school. The venue hosts shows most nights of the week, with different formats and teams performing. The school side offers classes in improv technique, ranging from absolute beginner to advanced levels. Both the shows and the classes are how IO makes money and how it builds its community of performers.

What happens at an IO Theater show
An IO show is a live performance where improv performers create scenes, games, and stories on stage with no script. The audience watches as performers respond to suggestions (often called "prompts") and build scenes together in real time. Different shows use different formats — some focus on short games, others on longer narrative scenes, and some mix both styles.
Shows typically run 45 minutes to an hour and happen most evenings and weekend afternoons. Ticket prices vary depending on the show and the venue location, but range from around $10 to $25 for most performances. Some shows are free or pay-what-you-wish, especially during slower times or for shows featuring newer performers still building their audience.
The performers on stage are usually either IO students, IO alumni, or visiting performers from other improv communities. Many performers use IO as a training ground and stepping stone to professional comedy work in television, film, or touring shows.
How IO classes work
IO offers improv classes structured in levels, starting with Level 1 (for people with no improv experience) and moving through higher levels as students build skills. Each level typically covers specific techniques — Level 1 might focus on basic scene work and listening, while higher levels cover more advanced formats, character work, or specific improv styles.
Classes meet once per week for four to eight weeks, depending on the session length. A typical class has 12 to 16 students and runs for two hours. The instructor leads exercises, watches students perform short scenes, and gives feedback. By the end of the course, students perform a short show for friends and family.
Class costs vary by location and level, but generally range from $200 to $400 per session. IO also offers workshops and intensive courses that cost more but cover material faster. Some locations offer payment plans or discounts for multiple classes taken in a row.
IO Theater locations and history
IO Theater was founded in Chicago in 1996 and remains headquartered there. The Chicago location is the largest and hosts the most shows and classes. IO has expanded to other cities over the years — there are IO locations in cities including Los Angeles, New York, and Washington D.C., though the number and size of these locations has changed over time.
The original name, ImprovOlympic, came from the founders' vision of improv as a competitive sport with "Olympic" levels of skill. The name was shortened to IO in 2018. The Chicago location is still the center of IO's training and performance, and many improv performers consider training there a significant part of their comedy education.
Who performs and studies at IO
IO attracts both complete beginners who want to try improv for fun and serious performers training for professional comedy careers. Many students take one or two classes out of curiosity, while others commit to the full sequence of levels and join performance teams.
Professional comedians, writers for television shows, and performers in touring improv companies often trained at IO or continue to perform there. The venue is known in the improv community as a place where the quality of teaching and performance is high, which is why it draws both students and audiences from across the country.
Attending a show versus taking a class
Attending a show requires only a ticket purchase and a time commitment of about an hour. You sit in the audience and watch performers work. This is the right choice if you want to see improv performed at a high level, enjoy live comedy, or are curious what improv looks like before committing to learning it yourself.
Taking a class requires a larger financial commitment (typically $200 to $400) and a weekly time commitment for four to eight weeks. You will perform on stage yourself, usually in short scenes during class and in a final show. This is the right choice if you want to learn improv technique, overcome stage fright, or explore whether comedy performance interests you.
Many people do both — they attend shows to see what they want to work toward, then take classes to build the skills. Others attend shows regularly without ever taking a class, and that is a perfectly valid way to enjoy improv.
How to find IO Theater information and register
IO Theater maintains a website for each location where you can see the current show schedule, read descriptions of each show, and buy tickets online. The website also lists class schedules, course descriptions, and pricing. You can register for classes directly through the website or by calling the venue.
Show tickets can usually be purchased online in advance or at the door on the night of the show, though popular shows may sell out. Class registration typically opens a few weeks before each session begins, and popular levels fill up quickly.
IO also maintains social media accounts where they announce new shows, special events, and student performances. Following these accounts is a good way to stay informed about what is happening at the venue.
Frequently Asked Questions
Do I need improv experience to attend an IO show?
No. IO shows are designed for audiences of all backgrounds. You do not need to know anything about improv to enjoy watching it. The performers will make the show entertaining whether you are seeing improv for the first time or you are an experienced performer yourself.
What if I have never done improv and I am nervous about taking a class?
Level 1 classes are designed specifically for people with no experience, and nervousness is completely normal. Most students in Level 1 are beginners feeling the same way. The instructor expects this and structures the class to build confidence gradually. Many people find that the fear of performing is worse than the actual experience.
Can I watch a class before I register?
Some IO locations allow you to observe a class before registering, though policies vary by location. Contact the venue directly to ask whether observation is possible. You can also attend a student show (usually held at the end of each session) to see what students learn and perform.
How much do IO Theater tickets usually cost?
Ticket prices typically range from $10 to $25 depending on the show, the performers, and the venue location. Some shows are free or pay-what-you-wish. Check the specific show listing on the IO website to see the price for the performance you want to attend.
Is IO Theater the only place to learn or watch improv?
No. Many cities have improv schools and performance venues besides IO. IO is one of the largest and most well-known, but other venues and schools teach improv and host shows. If there is no IO location near you, searching for "improv classes near me" or "improv shows near me" will show you other options in your area.
