 Vincent J. McMahon and Toots Mondt were very successful and soon controlled approximately 70% of the NWA's booking, largely due to their dominance in the heavily populated Northeastern United States.In 1963, McMahon and Mondt had a dispute with the NWA over "Nature Boy" Buddy Rogers being booked to hold the NWA World Heavyweight Championship.Both men left the company in protest and formed the World Wide Wrestling Federation (WWWF) in the process.
