The first routinized system for teaching church principles to potential proselytes had been created in 1953 and named "A Systematic Program for Teaching the Gospel". In 1961, this system was enhanced, expanded, and renamed "A Uniform System for Teaching Investigators". This new system, in the form of a hypothetical dialogue with a fictional character named "Mr. Brown", included intricate details for what to say in almost every situation. These routinized missionary discussions would be further refined in 1973 and 1986, and then de-emphasized in 2003.
