[17] Other varieties include: Worcestershire Sauce, Roast Chicken, Prawn Cocktail, Smoky Bacon, Tomato Ketchup, and Pickled Onion.

[18] The Leicester-born former England international footballer Gary Lineker has been the face of the brand since 1995, featuring in most of its popular commercials and successful advertising campaigns.

The Walkers brand (under PepsiCo) sponsors the UEFA Champions League and the Super Cup for the UK and Irish markets.

[21] In the 1880s, Henry Walker moved from Mansfield, Nottinghamshire to Leicester to take over an established butcher's shop in the High Street.

Meat rationing in the UK after World War II saw the factory output drop dramatically, and so in 1948, Walkers & Sons starting looking at alternative products.

[17] After Archer Martin and Richard Synge (while working in Leeds) received a Nobel Prize for the invention of partition chromatography in 1952, food scientists began to develop flavours via a gas chromatograph, a device that allowed scientists to understand chemical compounds behind complex flavours such as cheese.

[24] In 1954, the first flavoured crisps were invented by Joe “Spud” Murphy (owner of the Irish company Tayto) who developed a technique to add cheese and onion seasoning during production.

[31][32] In 2000, Lineker's Walkers commercials were ranked ninth in Channel 4’s UK wide poll of "The 100 Greatest TV Ads".

[35] In June 1999, PepsiCo transferred ownership of its Walkers brands out of Britain and into a Swiss subsidiary, Frito-Lay Trading GmbH.

Sensations flavours include Thai Sweet Chilli, Roast Chicken & Thyme, Balsamic Vinegar & Caramelised Onion.

[41] Walkers introduced the streaky bacon Quavers flavour to salt & vinegar and prawn cocktail in August 2002.

In summer 2009, Walkers launched its premium "Red Sky" brand of "all natural" potato crisps and snacks.

[47] For the 2011 Comic Relief, four celebrities (Jimmy Carr, Stephen Fry, Al Murray and Frank Skinner) each represented four new flavours.

Along with this packaging design, there came news that the company would begin using real meat products in its Smoky Bacon and Roast Chicken flavoured crisps.

[50] The public had to pick one of Walkers' ingredients as a base – Somerset Cheddar, Devonshire chicken, Norfolk pork, Dorset sour cream, Vale of Evesham tomatoes and Aberdeen Angus beef – and create a new flavour using it.

People voted on the Walkers website or used hashtags to see which flavour would be reintroduced permanently (Beef and Onion was chosen).

Over 100 entrants complained to the Advertising Standards Authority, who after completing an investigation, decided that elements were misleading, and the competition was banned.

Royal Mail was obliged by law to deliver the bags to Walkers' freepost address, but without envelopes they could not go through machines and had to be sorted by hand, causing delays.

Salt & Lineker was joined by Chicken Tackle Masala, Steak & Ale Pie-nalty, and Sweet Chili Kicker.

"[63] The confusion can be attributed to Walker's rise to become the most popular brand in the UK (overtaking Golden Wonder, whose colour scheme people had become used to) after their acquisition by PepsiCo in the 1990s.

Walkers' "Great British Dinner" range included baked ham & mustard and chicken tikka.

A series of "mystery flavours" were launched in 2012, and later revealed to be sour cream & spring onion, Lincolnshire sausage & brown sauce, and Birmingham chicken balti.

[65] In 2016, Walkers produced a limited edition 'Winners - Salt and Victory' crisps to commemorate its home-town football team, Leicester City, winning the Premier League for the first time.

[66] Earlier that season, Walkers had given Leicester fans in attendance at a match versus Chelsea bags of "Vardy salted" crisps, bearing the image of the Foxes' striker.

[71] According to the environmental charity Keep Britain Tidy, Walkers crisps packets along with Cadbury chocolate wrappers and Coca-Cola cans were the three top brands that were the most common pieces of rubbish found in UK streets in 2013.
