A brand of margarine spread, owned by Unilever. Introduced into the United Kingdom and Ireland from 1920, housewives were initially suspicious of the health affects and cooking ability of margarine. As a result, it required a large amount of advertising in the 1930s to increase usage, supported by the Stork sponsored Radio Lyons featuring the band of Carroll Gibbons. Stork has been manufactured at the Purfleet works (originally Van den Berghs & Jurgens) since 1920.
