Activia is a brand of yogurt owned by Groupe Danone and introduced in France in 1987. As of 2013, Activia is present in more than 70 countries and on 5 continents. Activia is classified as a functional food, designed to improve digestive health.
In the 1980s, Danone researchers took interest in bifidobacteria. They developed a specific strain that can survive in the acidic medium of yogurt. In addition to traditional yogurt bacteria, they decided to add a probiotic strain. From Wikipedia
