This, however, would change over the years and decades to come as professional wrestling grew and evolved. The American Wrestling Association, owned by Verne Gagne split off from the NWA and declared their primary singles title a world title in 1960. The World Wide Wrestling Federation, owned by Vince McMahon, Sr. followed suit in 1963 and declared their major singles title a world championship. Many other NWA affiliated promotions would split from the NWA over the years with Ted Turner's World Championship Wrestling in 1993, and Tod Gordon's Eastern Championship Wrestling in 1994. Each of these promotions declared their primary singles championship to be a world championship.
