80’s commercial for Farmer Browns snacks from Smiths.
Smith’s Potato Crisps Ltd. was formed by Frank Smith in the UK after World War I. The firm started in Cricklewood, London, reputedly in Smith’s garage. In 1927 the company expanded into a factory in Brentford, London. This was enlarged in 1930. During the depression Smith travelled to Australia to expand the business. Smiths was later owned by Nabisco, BSN and finally sold to Pepsico in the 1990s.
Subsequently Pepsico withdrew the brand, in favour of Walkers, which had been heavily marketed in a campaign using footballer Gary Lineker. Smiths is now largely controlled by Walkers Crisps in the UK. Many of the products owned by Smiths are now labelled as Walkers, although there are still several Smiths branded crisps.
