With the arrival of sound films and radio in the late 1920s, theater buildings were torn down or converted into film palaces. Soon the only theater that remained was provided by colleges and other amateur groups. It was not until the so-called cultural revolution swept the United States after World War II that a strong demand arose for resident professional theater. Then the demand led to action in almost every major city. With the help of the government and of such groups as the Ford and Rockefeller Foundations, regional theaters have been established on a non-profit basis to serve their communities as cultural not commercial institutions. Also active on the cultural scene are the arts councils of the fifty states. They provide funds and coordinate programs on the statewide level. On the local level, direct contributions to various art groups are made by many city governments. Professional plays are now being performed in such unusual places as a former nightclub in Boston, Massachusetts, or a wholesale meat-and-vegetable market in New Haven, Connecticut. But Broadway, off-Broadway, and regional theater, sometimes called resident theater, are still only part of the story of American theater today. There are touring companies taking Broadway shows to cities throughout the country. There are summer theaters — more than 300 now — where plays are performed, often in tents or barns. 21.
