The classification of theatres is governed by language in Actors' Equity Association contracts. To be eligible for a Tony, a production must be in a house with 500 seats or more and in the Theater District, which are the criteria that define Broadway theatre. Off-Broadway and Off-Off-Broadway shows often provide a more experimental, challenging, and intimate performance than is possible in the larger Broadway theatres. Some Broadway shows, however, such as the musicals Hair, Little Shop of Horrors, Spring Awakening, Next to Normal, Rent, Avenue Q, In the Heights, Fun Home, Dear Evan Hansen, and Hamilton, began their runs Off-Broadway and later transferred to Broadway, seeking to replicate their intimate experience in a larger theatre.
After, or even during, successful runs in Broadway theatres, producers often remount their productions with new casts and crew for the Broadway national tour, which travels to theatres in major cities across the country. Sometimes when a show closes on Broadway, the entire production, with most if not all of the original cast intact, is relaunched as a touring company, hence the name "Broadway national tour". Some shows may even have several touring companies out at a time, whether the show is still running in New York or not, with many companies "sitting down" in other major cities for their own extended runs.
Smaller cities may attract national touring companies, but for shorter periods they may even be serviced by "bus and truck" tours. These are scaled-down versions of the larger, national touring productions, historically acquiring their name because the casts generally traveled by bus instead of by air, while the sets and equipment traveled by truck. Tours of this type, which frequently feature a reduced physical production to accommodate smaller venues and tighter schedules, often run for weeks rather than months. Some will even play "split weeks", which are half a week in one town and the second half in another. On occasion, they will also play "one-nighters". The production values are usually less lavish than the typical Broadway national tour or national touring production and the actors, while still members of the actor's union, are compensated under a different, less lucrative union contract. The Touring Broadway Awards, presented by The Broadway League, honored excellence in touring Broadway.
