Other forms: collectivizations
When an industry is controlled by a collaborative group, instead of by individual private owners, it's called collectivization. The Soviet Union's 1930s policy of agricultural collectivization transformed many small farms into one enormous shared farm.
In economics, collectivization means forming collectives, or cooperative organizations, instead of allowing separate businesses to compete against each other. It's an important concept in communism, and Stalin's unsuccessful attempt at using collectivization to free peasants from poverty is often used as proof it can't work. Other kinds of collectivization have been more successful, though, from cooperative living situations to artist and worker collectives that give groups of people more support and bargaining power than they had as individuals.
