To be fair, Passbook savings accounts are still easily available in the U.S. They're mostly used for accounts directed towards youth, the elderly, migrant workers ("illegals"), Christmas clubs, and such. However, they're still offered to regular adult customers who simply want them.

I know down south a lot of church groups still use them to manage church funds, which means in some communities, even today, they can still actually make up 10%-20% of a banks total deposits.
