In the 1966–67 season, the competition was replaced by the Turkish Basketball Super League (BSL).

On April 25, 1955, the last game of the championship was Fenerbahçe against Galatasaray at Spor Sergi Sarayı.

Therefore, the last game was very important for both Galatasaray and Modaspor since the champion would be determined by total point difference.

In the game against Galatasaray, Fenerbahçe officials withdrew their team from the match with just 44 seconds left to the end of the match due to Fenerbahçe being behind by 13 points, with no chance of turning the game.

Nevertheless, the Federation of Sports declared that such behavior of the Fenerbahçe officials would not be acceptable and there were two domestic champions, Galatasaray and Modaspor, in that year.
