They returned under the banner of "World Championship Wrestling" presenting their first card on October 23, 1964, at the Sydney Stadium, and continued until 1974 when Barnett sold the promotion to Tony Kolonie and returned to the United States.
Barnett was a master at playing one wrestler against another. He was also prone to making outrageous statements, one being that he was a millionaire. While he lived like one, he had to dip into box office receipts to cover his high lifestyle. He was sued by wrestler, and booker Ole Anderson and had to come clean in a deposition that he was basically broke and never was worth a million dollars.
In later years, Barnett served as an adviser to the World Wrestling Federation (many credit him with masterminding the first three WrestleMania shows, which helped the organization establish their identity), Jim Crockett Promotions and World Championship Wrestling. (He was the man Ted Turner trusted the most in the business.)
Barnett was one of the few known men in wrestling who was openly gay..
Barnett is known for lying about having a love affair with famously gay actor Rock Hudson.
