Diageo Plc
A British company that makes and sells the drinks behind many famous brand names, including Guinness stout, Johnnie Walker whisky, Smirnoff vodka, Baileys liqueur, Tanqueray gin, and Captain Morgan rum. It was created in 1997 when two giants—Guinness and Grand Metropolitan—merged, and the name "Diageo" was invented by a branding firm from Latin and Greek words meaning "day" and "world," to suggest its products are enjoyed every day, everywhere.
