 With the emergence of trios ( tag teams consisting of three people ) such as Los <unk> de la Muerte , Los Brazos and more , the six @-@ man tag team match became increasingly popular in the early 1980s . Its popularity led to the trios format becoming the most prevalent match format in Lucha libre to this day . The popularity led to the creation of the first trios championship in Mexico when the Universal Wrestling Association ( UWA ) created the UWA World Trios Championship in 1984 . The Mexican National Trios Championship was created in 1985 , at the request of Empresa Mexicana de Lucha Libre ( EMLL ) and endorsed by the Mexico City Boxing and Wrestling Commission . The commission granted EMLL the rights to promote the championship , which meant that CMLL had control over the everyday use of the championship , determining which storylines the title <unk> being used in , who were allowed to challenge for the title and how to use it in a public relations sense . The Commission would oversee the rule and approves any championship change that EMLL proposed .
