John Johnnie Walker (1805 - 1857), began selling Scotch in his grocery store in Scotland. The brand became popular but only after his death the son Alexander Walker and nephew Alexander Walker junior became the main proponents of the commercialization of the scotch as a consumer product. With John Walker, the scotch sales amounted to 8% of the company's revenue; with the new business management by the sons of Alexander Walker, the percentage reached 90%. In 1865, John and his son Alexander began producing the first quality scotch, Walker's Old Highland. In 1870 Alexander Walker introduced the square bottle: this choice was made to make the most of the load surfaces, thus increasing the number of bottles that were exported, the other special feature of the bottle is the label, no longer horizontal but oblique. Between 1906 and 1909, the nephews of John, George and Alexander II, expanded the offer by adding three blended, also introducing the names based on color. Their company changed its name from Walker's Kilmarnock Whiskies to Johnnie Walker Whiskey. In 2012, after almost 200 years, the historic Kilmarnock factory was bought by Diageo, Johnnie Walker is today the best-selling scotch in the world.
