Ilatian wine glasses???

[reno wino]

Hey board, newbie here.
I always thaough it was my family, but I am starting to see this happening elsewhere, italian movies, Sopranos, etc...
Instead of drinking wine out of a proper wine glass, a small highball glass or collins glass is used. My Italian family members only drink wine from these (2nd gen americans), and even the polish side of my family (2nd geners as well) use these "jelly jar" glasses.
What gives? Do different cultures use non-stemmed wine glases, or is this an economic trait (are they really jelly jars)?
