[1] The dominant brand in the UK until the 1960s when Golden Wonder took over with Cheese & Onion, Smith's countered by creating Salt & Vinegar flavour (first tested by their north-east England subsidiary Tudor) which was launched nationally in 1967.

Deciding to make his own, Smith converted garages in Cricklewood, London into a crisp factory, selling to local businesses.

[5] Smith conceived the idea of selling unseasoned potato crisps with a small blue sachet of salt that could be sprinkled over them.

[6] In 1927, after buying Jim Viney's share of the business, the company expanded into a factory in Brentford, London.

In 1939, the footballers of Portsmouth won the last FA Cup final before the war on a daily diet of Smith's crisps.

[8][9] Smith's followed up this expansion two years later by purchasing the biscuit and wafer producer, G & T Bridgewater and the Cardiff based nut company Snackpak Food Products.

[10] Following the creation of Cheese & Onion flavour by Tayto in Ireland, Golden Wonder (Smiths' main competitor in Britain) produced their Cheese & Onion version, and Smith's countered with Salt & Vinegar (tested first by their north-east England subsidiary Tudor) which launched nationally in 1967, starting a two-decade-long flavour war.

[22] Smith's Crisps were first manufactured in Australia in 1931 with an associate, George Ensor, in leased premises in Sydney's Surry Hills.

They were originally made in 20 gas fired cooking pots, then packed by hand and distributed by Nestle confectionery vans.

[citation needed] In 1998, the Smiths Snackfood company was Australia's largest producer of salty snack foods.

It was acquired in August of that year, by Frito-Lay the second largest producer of salt snack foods in Australia, which is owned by PepsiCo.

[27] Products produced by The Smith's Snackfood Company have been recalled on several occasions including: In July 2016, The Smith's Snackfood Company was fined $10,800 by the Australian Competition & Consumer Commission for misleading representation on its Sakata Paws Pizza Supreme Rice Snacks, which included a logo with the words “Meets School Canteen Guidelines” and an image of a sandwich and apple.

The disclaimer that the product had only met the 'Amber' criteria of the National Healthy School Canteens Guidelines were in small font and on the other side of the packaging to the logo.
