## Founders
- **Charna Halpern**: Co-founder and longtime owner/artistic director; the organizational driving force and guide of the theater's mission
- **Del Close**: Co-founder, master teacher, and codifier of The Harold and long-form improv theory; died 1999; the philosophical and artistic anchor of iO's approach
- **David Shepard**: Creator of the original ImprovOlympic format; adapted Viola Spolin's Theater Games for competitive team improv

## Signature Form: The Harold
The Harold is iO's signature long-form improv piece — a structured-yet-free exploration of patterns, ideas, and emotions performed by an ensemble without a script. Developed and refined at iO, The Harold is now taught and performed at improv theaters worldwide. It is introduced in Level 1 and deepened in Level 4. Del Close is credited as its primary architect.

## Competitive Landscape (Chicago Comedy)
iO Theater, The Second City, and The Annoyance Theatre form Chicago's "comedy triangle." iO is specifically distinguished by its commitment to long-form improv (vs. Second City's sketch-and-revue format). iO is frequently cited as the birthplace of the Harold and the crucible of contemporary long-form technique. Many performers train at both iO and Second City.

## Notable Alumni
iO has trained many of America's most recognized comedic performers and writers, including: Amy Poehler, Tina Fey, Mike Myers, Jason Sudeikis, Seth Meyers, Rachel Dratch, Aidy Bryant, Angela Kinsey, Kate Flannery, Neil Flynn, Jack McBrayer, Scott Adsit, David Koechner, Andy Richter, Tim Meadows, Chris Farley, Ike Barinholtz, Arden Myrin, Mo Collins, Stephen Colbert, Adam McKay, and many others who went on to SNL, film, and television.

Note: Many alumni trained at both iO and Second City. Attribution should be verified before asserting exclusive iO training.
