Even today, despite the tournament maintaining a consistent structure for 8 years, it is harder to find score updates on major European newspapers such as the "International Herald Tribune" or "L'Équipe" than it is for the Argentinian championships. And of course this has contributed to lack of major reference about the clubs themselves, as on top of these variations the Brazilian championship is among the most balanced in the world with its Clube dos 13, the greatest football clubs of Brazil, and other competitive clubs and as rivalries are often based in details. To better understand Brazilian football, a brief history of the "Brazilian soccer national-league tournament-scheduling history" is explained below on a yearly basis, with emphasis on technical aspects. Tables with final placings and a straightforward ranking based on simple rules are also provided as CBF rules for official placings have so far reflected the troubled tournament's history and as no official ranking from CBF is publicly available, let alone in detail.
