Oikos is a brand of Danone, the world's largest yogurt producer, and has the third-largest Greek yogurt market share in the United States. Oekos was originally a brand under the Stonyfield trademark, but Danone's acquisition of Stonyfield transformed it into a Greek-style yogurt brand, making it the only yogurt commercial for the SuperBowl.
 
In the U.S. Consumer Reports, Oikos Original Full-Fat Greek Yogurt ranked first with a score of 87. OikosTRIPLEZERO is named because it has no added sucrose, artificial sweeteners and fats, contains 10g of protein per 100g of yogurt, and currently has more than 10 flavors to choose from, taking into account nutrition and taste, suitable for people who are afraid of gaining weight. The taste of Oekos yogurt varies from country to country, Danone's yoghurt is relatively cost-effective, and the Chinese market can only see Oekos Greek yogurt in some imported stores.
