Boursin cheese was first produced in 1957 by François Boursin in Normandy. Boursin is a trademark – Boursin cheese was at one time produced exclusively in Croisy-sur-Eure, France, by the Boursin company, a subsidiary of Group Bel, which purchased Boursin on 2007-11-05 for 400 million euros. The cheese is also produced in the United States for North American distribution by Unilever.
