Template:Infobox Co-operative Founded in 1916 as the Cooperative League of America, the National Cooperative Business Association (NCBA) is a United States membership organization for cooperatives, businesses that are jointly-owned and democratically-controlled
The league's founding president was medical doctor James Peter Warbasse, who served in that role until 1941. In its first few decades, it focused on consumer cooperation, and published a monthly magazine, Co-operation. In 1922, it originated and trademarked the twin pines symbol used to represent North American cooperatives.
In 2000 the group successfully lobbied the Internet Corporation for Assigned Names and Numbers to establish a new top-level domain exclusively for business cooperations. The domain, .coop, became active in 2002.
