Over the years the anniversary show would become the biggest show of the year for CMLL, akin to the Super Bowl for the National Football League (NFL) or WWE's WrestleMania event. The first anniversary show was held in Arena Modelo, which Lutteroth had bought after starting EMLL. In 1942–43 Lutteroth financed the construction of Arena Coliseo, which opened in April 1943. The EMLL 10th Anniversary Show was the first of the anniversary shows to be held in Arena Coliseo. In 1956 Lutteroth had Arena México built in the location of the original Arena Modelo, making Arena México the main venue of EMLL from that point on. Starting with the EMLL 23rd Anniversary Show, all anniversary shows except for the EMLL 46th Anniversary Show have been held in the arena that would become known as "The Cathedral of Lucha Libre". On occasion EMLL held more than one show labeled as their "Anniversary" show, such as two 33rd Anniversary Shows in 1966. Over time the anniversary show series became the oldest, longest-running annual professional wrestling show. In comparison, WWE's WrestleMania is only the fourth oldest still promoted show (CMLL's Arena Coliseo Anniversary Show and Arena México anniversary shows being second and third). EMLL was supposed to hold the EMLL 52nd Anniversary Show on September 20, 1985, but Mexico City was hit by a magnitude 8.0 earthquake. EMLL canceled the event both because of the general devastation but also over fears that Arena México might not be structurally sound after the earthquake.
