For most people the longest surviving artifact of the denomination was the TV quiz show called "Miliard w rozumie" (A billion in the mind) which had a grand prize of 1 000 000 000 old zł, i.e. 100 000 new zł)

It was a great show, pity it's long gone. Certainly better than shitty entertainment we got now - and at the same time not as pretentious as "Wielka gra".
