From the mid-eighties through 1992 Kevin Clancy and Professor Joseph Blackburn developed and published a validated simulated test marketing model that married sophisticated marketing mix modeling (The BBDO NEWS model) with laboratory simulation research (The Yankelovich Laboratory Test Market). This model, called LITMUS, was designed to forecast the monthly performance of a new product or new service in terms of awareness, consideration, trial, repeat usage, revenues, market share and profitability before any investments are made in the real world. The evolving model was employed by many firms over a 15 year period. One of its most unique features was its ability to optimize marketing plans. Using mathematical programming algorithms, the model had the capability to explore literally billions of alternative plans in order to find those forecast to be the most profitable. From the mid-eighties through 1992, LITMUS was presented at numerous academic and professional conferences and published in academic papers and in the book, Simulated Test Marketing: Technology for Launching Successful New Products (with Robert S. Shulman and Marianne Wolf), New York: Lexington Books – A Division of Macmillan, Inc.,(1994)
