Drama theory was devised by professor Nigel Howard in the early 1990s and, since then, has been turned to defense, political, health, industrial relations and commercial applications. Drama theory is an extension of Howard's metagame analysis work developed at the University of Pennsylvania in the late 1960s, and presented formally in his book "Paradoxes of Rationality", published by MIT Press. Metagame analysis was originally used to advise on the Strategic Arms Limitation Talks (SALT).
