Repertory companies
While most modern theatre companies rehearse one piece of theatre at a time, perform that piece for a set "run", retire the piece, and begin rehearsing a new show, repertory companies rehearse multiple shows at one time. These companies are able to perform these various pieces upon request and often perform works for years before retiring them. Most dance companies operate on this repertory system. The Royal National Theatre in London performs on a repertory system.
