In the early 20th century, the U.S. was a very important market for Bushmills (and other Irish Whiskey producers). American Prohibition in 1920 came as a large blow to the Irish Whiskey industry, but Bushmills managed to survive. Wilson Boyd, Bushmills' director at the time, predicted the end of prohibition and had large stores of whiskey ready to export. After the Second World War, the distillery was bought by Isaac Wolfson, and, in 1972, it was taken over by Irish Distillers, meaning that Irish Distillers controlled the production of all Irish whiskey at the time. In June 1988, Irish Distillers was bought by French liquor group Pernod Ricard.
