Can't find any long lasting ones. For example, hippie communes were common in the 60's and 70's. They've all vanished. The largest, San Francisco's 1967 "summer of love", only lasted a few months before collapsing.
"those who gathered in Haight-Ashbury during 1967 allegedly rejected the conformist and materialist values of modern life; there was an emphasis on sharing and community. The Diggers established a Free Store, and a Free Clinic where medical treatment was provided."
It's a survivor of "thousands" of communes started in the 60s and 70s, perhaps the only one. Turnover is about 12% a year. Perhaps the secret to their success is the ability to attract a constant stream of replacements, as members who tire of communism leave.
Even so, it shows that if you want to live in a communist society, you're free to form one here in America.
Israeli kibbutzim is probably the largest example, where you have a set of many communes so you can see what is an accident and how the average behaves; and they were/are long lasting.
