The first academic department with the name "Performance Studies" started at NYU in 1980. Shortly after in 1984 Northwestern University renamed its long-standing Department of Interpretation as the "Department of Performance Studies;" finally reflect their broadened definition of text and performance. Generally the differences between the NYU and Northwestern models cite different disciplinary concerns, however, in both instances a focus on practice lead to research methodologies and theories beyond theatre or literature in relation to or in service of understanding performance. For more information on the different origins and disciplinary traditions of performance studies see Shannon Jackson's book "Professing Performance" and the introductory chapter in Nathan Stucky and Cynthia Wimmer's "Teaching Performance Studies".
