Brendan O'Regan established the world's first duty-free shop at Shannon Airport in Ireland in 1947; it remains in operation today. Designed to provide a service for trans-Atlantic airline passengers typically travelling between Europe and North America whose flights stopped for refuelling on outbound and inbound legs of their journeys, it was an immediate success and has been copied worldwide. Thirteen years later, two American entrepreneurs, Charles Feeney and Robert Warren Miller, founded what is now Duty Free Shoppers (DFS) on 7 November 1960. DFS started operations in Hong Kong and spread to Europe and other places around the globe. Securing the exclusive concession for duty-free sales in Hawaii in the early-1960s was a commercial breakthrough for DFS, which enabled the company to focus on Japanese travelers. DFS continued to innovate, expanding into off-airport duty-free stores and into large downtown Galleria stores; it grew to become the world's largest travel retailer. In 1996 LVMH Moët Hennessy Louis Vuitton acquired the interests of Feeney and two other shareholders and jointly owned DFS with Miller.
