The name P.O.K. is currently used to allude to the continuing dominance of the three clubs in the National A Division. Rarely does a team outside these three finish in the top three spots of the Championship; doing so is called "breaking the P.O.K.". Since 1928, only three other teams - Aris F.C., AE Larissa and PAOK FC - have won the Greek Championship. Finally, on March 7, 1963, the POK officially ceased to exist. The entry of the teams in the bulletins of PRO-PO, the establishment of the A 'national category and the participation of the Greek teams in the European football cups, made this institution weaken and finally to be abolished.
