On a great British summers day, we took a group of mates to have fun on the world's largest inflatable bag of Walkers crisps. #CantHelpButSmile. Walkers is a British snack food manufacturer mainly operating in the United Kingdom and Ireland. Walkers was founded in 1948 in Leicester, England by Henry Walker, and acquired by Lay's owner, Frito-Lay, a division of PepsiCo, in 1989. It is best known for manufacturing potato crisps, and other, non-potato-based snack foods. They hold 56 per cent of the British crisps market. The Walkers site in Leicester is the largest crisp production plant in the world, producing over 11 million bags of crisps per day and using about 800 tons of potatoes. In the 1880s, Walker moved from Mansfield to Leicester to take over an established butcher's shop in the high street. Meat rationing after World War II saw the factory output drop dramatically, and so in 1948 the company starting looking at alternative products. Potato crisps were becoming increasingly popular with the public, leading managing director R.E. Gerrard to shift the company focus and begin hand-slicing and frying potatoes.
