Bon Appétit is an American food and entertaining magazine that is published monthly by Condé Nast. It was started in 1956 and became a bimonthly magazine in December 1956 in Chicago. The magazine was acquired by M. Frank Jones in Kansas City, Missouri in 1965. Jones was owner, editor and publisher until 1970, when Bon Appétit was merged into the Pillsbury Company, who sold it to Knapp Communications, publishers of Architectural Digest, four years later. Condé Nast Publications, the current owners, purchased Knapp Communications in 1993. Its sister publication was Gourmet, before the latter was discontinued in October 2009. The magazine's headquarters, which had been in Los Angeles, CA, were moved to New York City in early 2011.
