Stonyfield Farm, also simply called Stonyfield, is an organic yogurt maker located in Londonderry, New Hampshire, USA. Stonyfield Farm was founded by Samuel Kaymen in 1983, in Wilton, New Hampshire, as an organic farming school. The company makes the number-one selling brand of organic yogurt and number-three overall yogurt brand in the United States, according to Fortune magazine. It owns brands including YoBaby, YoToddler, YoKids and Oikos. In 2001, Groupe Danone, a France-based food product company whose brands include Evian bottled water and Danone/Dannon yogurt, purchased an initial 40% of Stonyfield shares. This was followed in late 2003 with an additional purchase such that Group Danone now owns about 85% of Stonyfield shares.
