<P> The brand became popular, but after Walker's death it was his son Alexander' Alec' Walker and grandson Alexander Walker II who were largely responsible for establishing the whisky as a favoured brand . The Spirits Act of 1860 legalised the blending of grain whiskies with malt whiskies and ushered in the modern era of blended Scotch whisky . Andrew Usher of Edinburgh, Scotland, was the first to capitalise on blended Scotch whisky, a more accessible whisky that was lighter and sweeter in character, making it much more marketable to a wider audience, followed by the Walkers in due course . </P> <P> Alexander Walker had introduced the brand's signature square bottle in 1860 . This meant more bottles fitting the same space and fewer broken bottles . The other identifying characteristic of the Johnnie Walker bottle was--and still is--the label, which, since that year, is applied at an angle of 24 degrees upwards left to right and allows text to be made larger and more visible . This also allowed consumers to identify it at a distance . One major factor in his favour was the arrival of a railway in Kilmarnock, carrying goods to merchant ships travelling the world . Thanks to Alec's business acumen, sales of Walker's Kilmarnock reached 100,000 gallons (450,000 litres) per year by 1862 . </P> <P> In 1865, Alec created Johnnie Walker's first commercial blend and called it Old Highland Whisky, before registering it as such in 1867 . </P> <P> Under John Walker, whisky sales represented eight percent of the firm's income; by the time Alexander was ready to pass on the company to his own sons, that figure had increased to between 90 and 95 percent . </P>
