In 1964, 100,000 French farmers merged their regional dairy cooperatives to sell nationally. In 1965, two co-ops, “Yola” and “Coplait”, merged, becoming “Yoplait”. Their logo is a six-petaled flower designed by Phlippe Morlighem,  each petal representing one of the six main cooperatives founders. According to the logo image above, the flower now only has five petals.

On May 18, 2011, General Mills announced it had agreed to purchase a controlling interest in Yoplait SAS.   The announcement of the completion of the acquisition was made on 1 July 2011.
