Examples Of American Realism Theater?

I found a nice definition of realism in theatre: " It is where people move and talk in a manner similar to that of our everyday behavior. The style has been dominant for the last 120 years. It holds the idea of the stage as an environment, rather than as an acting platform." (http://homepage.smc.edu/jones_janie/TA%202/8Realism.htm)

The plays of Eugene O'Neill, August Wilson, Tenessee Williams, Arthur Miller, and David Mamet are excellent examples of realism in American theatre.
