By the 2000s, major promotions like the WWE have favoured elevating the careers of wrestlers who are able to speak for themselves. As a result, the previously ubiquitous role of a manager has declined in favor of either female valets who occasionally get involved in wrestling matches, or by people who hold on-screen power as General Managers, Commissioners or various corporate officer positions. However, contemporary wrestling personalities such as Paul Heyman and Vickie Guerrero have demonstrated that managers are still effective at drawing heat, and when used judiciously, are capable of changing the tone and inner workings of a wrestling match by contributing drama and tension.
