Amul was formed in 1946 as a dairy cooperative in India. It is owned by 3 million milk producers and led to India becoming the largest milk producer in the world. Amul has over 150 chilling centers and is the largest food brand in India, controlling over 50% market share in products like butter, cheese, and sweets. Amul's success is attributed to its cooperative model where milk producers control procurement, processing, and marketing with professional management.
