While watching The Sopranos I see every house having an electric kettle. Is it more common for Italian-Americans to have them? A New Jersey thing? Or are these more common than thought by the overseas tea drinkers?

Was always told Americans don't generally have electric kettles becasue of reasons (120V, non loose leaf tea drinkers, etc take your pick)

But while watching The Sopranos I saw every household with an electric kettle.

Is this an misconception or an Italian-American thing to need an electric kettle. Or…?

Edit: Thanks for your answers. Didn't know people were so sensitive about the 110-120V (yes, I've seen the Technology Connection video). Anyway..Thanks to u/thorazos for actually trying to answer my question and it looks like they are coffee carafes and not electric kettles.
