Up until the mid-1990s, managers were very common because they served a secondary purpose: "getting heat." During the territorial era, most managers did not travel from territory to territory, but instead remained in one territory to provide instant heat to the promotion's new heel acts. Notable examples include "The Mouth of The South" Jimmy Hart in Memphis, Bobby "The Brain" Heenan in the American Wrestling Association, and the "Three Wise Men" (Lou Albano, Freddie Blassie, and The Grand Wizard) in the World Wide Wrestling Federation (now the WWE).
