Girl Scout cookies are made by large national commercial bakeries under license from Girl Scouts of the USA. The bakers licensed by the organization may change from year to year, though this is not common. In 2008 the licensed companies were Little Brownie Bakers (LBB), a subsidiary of Keebler, which is owned by Kellogg's; and ABC Bakers, a subsidiary of Interbake Foods, which is owned by George Weston Limited.[10][11][12] ABC Bakers has been licensed to produce Girl Scout cookies since 1936.
