Particularly in the 1960s, and again in the 1990s, both Schechner and TDR challenged traditional, prevailing ideas about theater-what it is, how it should be presented, and the ritual and ideals behind it.

He is widely recognized as the founder of "performance studies" as an academic discipline. In the process of working out what performance studies is, Schechner and his colleagues at New York University created new ideas and new ways of thinking that still affect today's world of performance, theater, dance, and the social sciences. As "the journal of performance studies," TDR did much to shape the new discipline.
