Notable events

• Lee Haney won his seventh consecutive Mr. Olympia title
• This was the first edition of Mr. Olympia to employ drug tests. Amid criticism by spectators for lowering the quality of the event, the IFBB reversed its decision the following year.^[2]
• World Wrestling Federation (WWF) owner Vince McMahon and bodybuilder Tom Platz bought a booth at the competition as representatives of a new magazine known as Bodybuilding Lifestyles. However, when Platz appeared on-stage as its representative during the closing ceremonies, he announced the formation of the World Bodybuilding Federation—a short-lived competitor to the IFBB backed by WWF parent company Titan Sports.^[3][4]
