iO (formerly known as ImprovOlympic) teaches classes on and hosts performances of improv comedy. Its main focus is on long-form improv (that's when a crew improvises for at least 25 minutes. In short-form, each skit is interrupted by audience suggestions or only plays out for a scene). The theater hosts several events daily, with famous guests and alumni popping in all the time.
