Shubert family
The Shubert family, of brothers Lee, Sam, and Jacob, was a central force in the establishment and expansion of both the legitimate theatre and vaudeville in the United States in the first half of the 20th century. By 1924, the Shubert Organization they founded controlled 75 percent of all American theatres, producing 25 percent of all plays, triggering the creation of Actor's Equity as a performing arts labor union in backlash. The organization's dominance resulted in a mid-1950s Supreme Court antitrust ruling forcing the brothers to partially divest their empire.
As of 2024, the Shubert Organization owns 17 Broadway theaters in New York City's Theater District, still the hub of the theatre industry in America, as well as off-Broadway venues and theatres in Boston and Philadelphia.
