 The WWWF World Heavyweight Championship was then established and awarded to Buddy Rogers with the explanation that he won a fictional tournament in Rio de Janeiro, supposedly defeating Antonino Rocca in the finals.After several years, the WWWF became affiliated with the NWA once again, and "World" was dropped from the championship's name.In 1979, the WWWF was renamed World Wrestling Federation (WWF), and then after conclusively ending its affiliation with the NWA in 1983, the championship became known as the WWF World Heavyweight Championship.
