Formed in 1997 through the merger of Grand Metropolitan and Guinness, Diageo is the largest distiller globally by sales. Diageo acquired some of the Seagram assets in 2001, which gave it brands such as Captain Morgan rum and Crown Royal Canadian whisky. Since then, mergers and acquisitions have mostly been bolt-on in nature, plugging gaps in the company's product and geographic portfolio.
