Vivendi SA (formerly known as Vivendi Universal) is a French multinational mass media and telecommunication company headquartered in Paris, France. The company has activities in music, television and film, publishing, telecommunications, the Internet, and video games.

On December 14, 1853, a water company named Compagnie Générale des Eaux (CGE) was created by an Imperial decree of Napoleon III. In 1854, CGE obtained a concession in order to supply water to the public in Lyon, serving in this capacity for over a hundred years. In 1861, it obtained a 50-year concession with the City of Paris.

For more than a century, Compagnie Générale des Eaux remained largely focused on the water sector. However, following the appointment of Guy Dejouany as CEO in 1976, CGE extended its activities into other sectors with a series of takeovers. Beginning in 1980, CGE began diversifying its operations from water into waste management, energy, transport services, and construction and property. It acquired the Compagnie Générale d'Entreprises Automobiles (CGEA), specialized in industrial vehicles, which was later divided into two branches: Connex and Onyx Environnement. CGE then acquired the Compagnie Générale de Chauffe, and later the Montenay group. The Energy Services division these companies became part of, was later (1998) renamed Dalkia.
