70,000 spectators. Despite the large investment and initial success of the team, the Chileans would be defeated in the last match by eventual champions Argentina. Uruguay hosted and won the 1942 edition. Chile would host again in 1945, and came close to playing for the title against Argentina. However, Brazil spoiled that possibility, and Argentina would win the tournament once again on Chilean soil. The event then entered a period of great disruption. The championship was not played on a regular basis and many editions would be deemed unofficial, only to be considered valid later on by CONMEBOL. For example, Argentina would be the first (and so far only) team to win three consecutive titles by winning the championships of 1945, 1946 and 1947. After those three annual tournaments, the competition returned to being held every two years, then three and later four. There were even two tournaments held in 1959, one in Argentina and a second in Ecuador. During this period, some of the national teams were indifferent to the tournament. Some did not participate every year, others sent lesser teams; in the 1959 edition held in Ecuador, Brazil entered a team from the state of Pernambuco. Bolivia won for the first time when it hosted in 1963, but was defeated in the first game of the 1967 tournament by debutant Venezuela. The founding of the Copa Libertadores in 1959 also affected the way the tournament was viewed by its participants. After eight years of absence, the event resumed in 1975 and officially acquired the name Copa América. The tournament had no fixed venue, and all matches were played throughout the year in each country. Nine teams participated in the group stages with the defending champions receiving a bye into the semifinals. The tournament was contested every four years using this system until 1987. Renewal In 1986, CONMEBOL decided to return to having one country host the tournament and to contest it every other year. From 1987 until 2001, the event was hosted every two years in rotation by the ten members of the confederation. The format would remain constant with a first round of groups, but the final round stage ranged from being a new, final round-robin group or a single-elimination system to decide the winner. This renewal helped the tournament, which began to receive television coverage in Europe and North America. The 1987 Copa América was held
