IRT meaning in Community ?

Indiana Repertory Theatre, frequently abbreviated IRT, is a professional regional theatre in Indianapolis, Indiana that began as a genuine repertory theatre with its casts performing in multiple shows at once. It has subsequently become a regional theatre and a member of the League of Resident Theatres. A standard season typically consists of nine or ten plays on two different stages (with at least two selected especially although not exclusively for student audiences, one of which is often a Shakespeare play) and the bulk of its season (including a holiday show, usually Charles Dickens's A Christmas Carol) performed on the OneAmerica Stage.

The theatre company has history in two theatre buildings. It began in 1972 in The Athenaeum. In 1980, the IRT moved to its current home, The Indiana Theatre, a former Paramount Pictures Publix Theatre at 140 West Washington Street, built in 1927 and converted from a movie theater for IRT's use.
