Basketball Bundesliga was replaced by two geographical divisions (North and South).

Basketball Bundesliga now consists of two leagues, ProA and ProB.

[1] On May 3, 1974, the DBB Bundestag in Cologne decided, with only three votes against, to introduce the single-tier Basketball Bundesliga and the two-tier 2nd Bundesliga starting with the 1975-76 season.

Since then, the league has been the second highest division in German basketball (below the BBL which has existed since 1966).

It was restructured to professionalize the clubs, increase the level of play and make promotion to the Basketball Bundesliga easier.
