The history of contemporary American theatre design, that is, the design of scenery, costumes, and lighting in the United States after World War II, can actually be traced back to the production of The Man Who Married a Dumb Wife. A critical event in the history of costume design was the actors' strike in 1919 for better wages and improved working conditions. One of the key figures in the early history of lighting design is Stanley R. McCandless. One of the major factors in the globalization process was the proliferation of theatre activity that occurred between 1965, when the National Endowment for the Arts was founded, and the mid-eighties. The design of rock concerts, and how the design of rock concert lighting consequently influenced theatre design, is a fascinating phenomenon. The twentieth century has witnessed great advances in the way theatre productions have been designed.
