Land O'Lakes was founded in 1921 in Saint Paul, Minnesota, by representatives from 320 co-op creameries as the Minnesota Cooperative Creameries Association. This organization aimed to improve marketing and quality of butter, and thus increase the profitability of dairying. The Association developed and implemented the systematic inspection, grading and certification of butter from member creameries, resulting in greater uniformity of product. The improved quality and uniformity, and the reliability of its grading system, were touted in advertising materials. In 1924, the uniformly graded sweet cream butter was given the name "Land O'Lakes" after a contest, and the certificate forms used by the Association included the "Land O Lakes" marketing name (Minnesota's state nickname is "Land of 10,000 Lakes").
The name became so popular that the organization's public identity was often confused with its product name; thus, in 1926, the organization itself adopted the name "Land O' Lakes Creameries, Inc." and became synonymous with its product.
The company was often accused of unfair competition and false advertising in its early years, and compelled to defend its inspection and certification processes. Eventually, however, the sweet butter marketing strategy drove competitors either to match the quality of butter produced under the Land O' Lakes name or see their sales decline. Many competitors in the dairy products business copied the Land O' Lakes approach, and the certification of quality became a tried and true marketing technique in other product lines as well.
The Land O' Lakes company has grown through numerous acquisitions, and now has a large business in farm supply in addition to dairy.
The company is made up of four segments: Dairy Foods, Animal Feed, Crop Seed and Crop Protection and Layers (eggs). Dairy Foods markets and manufacturers butter and cheese to the industrial, retail, foodservice and international channels.
Land O'Lakes butter packaging is familiar to U.S. consumers, and had a noticeable impact on 20th century U.S. culture.
