In 1953, Salvador Lutteroth joined the US based National Wrestling Alliance (NWA), becoming the official NWA territory for all of Mexico, known as "NWA-EMLL" outside Mexico. By joining the NWA, Lutteroth and EMLL gained control of the NWA World Light Heavyweight Championship. They were also able to re-brand their "World Middleweight Championship" to become the NWA World Middleweight Championship and their "World Welterweight Championship" became the NWA World Welterweight Championship. In the early 1950s television became as a viable entertainment medium in Mexico which was set to bolster the popularity of EMLL, but Arena Coliseo was not equipped properly for television transmissions. As it turns out luck was on Lutteroth and EMLL's side as Lutteroth and the personnel at Arena Coliseo bought a lottery ticket worth 5 million Pesos. Lutteroth used his portion of the winnings to finance the construction of Arena México, on the location where Arena Modelo used to sit. Arena México enabled EMLL to broadcast their weekly wrestling shows across Mexico, yielding a popularity explosion for the sport. Starting in 1956, with the EMLL 23rd Anniversary Show all anniversary shows were held in Arena México, except the EMLL 46th Anniversary Show. Over time the arena became known as "The Cathedral of Lucha Libre".
