[1] In the year before, Genevan newspaper La Suisse Sportive organized the first unofficial Swiss Championship, where the Coupe Ruinart was awarded to Grasshopper Club Zürich.

The final game was held between Cantonal Lausanne, FC Bern, and Vereinigte St. Gallen, with Cantonal Lausanne beating first FC Bern 2-0 and then Vereinigte St. Gallen 3-2 to win the championship.

These name changes came as a push to create the aforementioned National League, which no longer would be split into regional groups.

This reorganization was finally realized for the 1933–34 season, however the First League maintained regional groups.

At the same time the NLB was increased to 24 teams, split once again into two regional groups.

During the promotion/relegation stage, the bottom four teams of the NLA would be joined by the top six of both groups.

Starting with the 1995–96 season, the NLB was once again reunited and slimmed down to twelve teams.

Both playoffs would be played in a round-robin group with eight teams, with the top four promoted/remaining in the NLA and NLB, respectively.

At the beginning of the 20th century, further format changes to the top Swiss leagues were suggested.

To make the league more attractive to viewers, it was reduced again to 16 participants in 2008 and then further down to ten in 2012.

FC Sion were not awarded a license for the 2003–04 season resulted in an extra team being promoted.
