[7][8] On March 5, 1959, at the 24th South American Congress held in Buenos Aires, the competition was ratified by the International Affairs Committee.[3][9] For the 2019 edition, the different stages of the competition were contested by the following teams:[3] Bolivia Ecuador Paraguay Peru Uruguay VenezuelaThe winners of the previous season's Copa Libertadores are given an additional entry to the group stage even if they do not qualify for the tournament through their domestic performance; however, if the title holders qualify for the tournament through their domestic performance, an additional entry is granted to the next eligible team, "replacing" the titleholder.Because Europe and South America are considered the strongest centers of the sport, the champions of those continents enter the tournament at the semifinal stage.It was designed by goldsmith Alberto de Gasperi, an Italian-born immigrant to Peru, in Camusso Jewelry in Lima at the behest of CONMEBOL.The project normally starts after the club wins its national league (which grants them the right to compete in the following year's Copa Libertadores).In 2010, players from Guadalajara stated that they would rather play in the Copa Libertadores final than appear in a friendly against Spain, then reigning world champions,[15] and dispute their national league.[17] Former Boca Juniors goalkeeper Óscar Córdoba has stated that the Copa Libertadores was the most prestigious trophy he won in his career (above the Argentine league, Intercontinental Cup, etc.)[18] Since its inception in 1960, the Copa Libertadores had predominantly been won by clubs from nations with an Atlantic coast: Argentina, Brazil and Uruguay.The first club from a country with a Pacific coast to reach a final was Universitario of Lima, Peru, who lost in 1972 against Independiente of Argentina.[19] Atletico Nacional of Medellín, Colombia, won the Copa Libertadores in 1989, becoming the first nation with a Pacific coastline to win the tournament.Other clubs from nations with Pacific coastlines to have won the competition are Colo-Colo of Chile in 1991, Once Caldas of Colombia in 2004, and LDU Quito of Ecuador in 2008.Matches are broadcast in over 135 countries, with commentary in more than 30 languages, and thus the Copa is often considered one of the most watched sports events on TV;[21] From 1997 to 2017, the competition had a single main sponsor for naming rights.[23] The third and final title sponsor was Bridgestone, who signed a sponsorship deal for naming rights for a period of five years from 2013 edition to 2017.The data below does not include the 1948 South American Championship of Champions, as it is not listed by Conmebol either as a Copa Libertadores edition or as an official competition.
