I don't remember the exact year, but Bialys got some not insignificant attention in the media around the time the the Sopranos was being produced. This may have been an influence, or it may simply have been the show putting light on a beloved, but not-well-known comestible.

Mel Brooks was undoubtedly referring to the food in choosing this name.
(Also "Biały is Polish for "white". The word is a Polish surname, as well as a nickname of several Polish monarchs and noblemen.")
