recent years, some shows have moved their Tuesday show time an hour earlier to 7:00 pm. The rationale for this move was that since fewer tourists take in shows midweek, Tuesday attendance depends more on local patrons. The earlier curtain makes it possible for suburban patrons to get home by a reasonable hour after the show. Some shows, especially those produced by Disney, change their performance schedules fairly frequently depending on the season. This is done in order to maximize access to their target audience. Producers and theatre owners Most Broadway producers and theatre owners are members of The Broadway League (formerly "The League of American Theatres and Producers"), a trade organization that promotes Broadway theatre as a whole, negotiates contracts with the various theatrical unions and agreements with the guilds, and co-administers the Tony Awards with the American Theatre Wing, a service organization. While the League and the theatrical unions are sometimes at loggerheads during those periods when new contracts are being negotiated, they also cooperate on many projects and events designed to promote professional theatre in New York. Of the four non-profit theatre companies with Broadway theatres, all four (Lincoln Center Theater, Manhattan Theatre Club, Roundabout Theatre Company, and Second Stage Theatre) belong to the League of Resident Theatres and have contracts with the theatrical unions which are negotiated separately from the other Broadway theatre and producers. (Disney also negotiates apart from the League, as did Livent before it closed down its operations.) The majority of Broadway theatres are owned or managed by three organizations: the Shubert Organization, a for-profit arm of the non-profit Shubert Foundation, which owns seventeen theatres; the Nederlander Organization, which controls nine theatres; and Jujamcyn, which owns five Broadway houses. Personnel Both musicals and stage-plays on Broadway often rely on casting well-known performers in leading roles to draw larger audiences or bring in new audience members to the theatre. Actors from movies and television are frequently cast for the revivals of Broadway shows or are used to replace actors leaving a cast. There are still, however, performers who are primarily stage actors, spending most of their time "on the boards", and appearing in television and screen roles only secondarily. As Patrick Healy of The New York Times noted: Broadway once had many homegrown stars who committed to working on a show for a year, as Nathan Lane has for The Addams Family. In 2010,
