It's a savoury snack loved by the nation, but over time, UK supermarkets have changed or phased out countless crisps that were once beloved by Britons.Earlier this week, a man made social media users nostalgic for old-school crisps after he found a Golden Wonder packet from what he believes to be the 1970s.Talking to X, Donnie Maclean, from Scotland, explained that he found the bacon-flavoured crisps while renovating his kitchen.'Hey @GoldenWonderUK, I'm renovating the house I bought recently. I just pulled a kitchen unit away from the wall and found these beauties,' he wrote, adding, 'I'm estimating the late 1970s. What do you reckon?!'The post gained one million views, with people marvelling at the packet, including how full it was, and the seemingly much shorter ingredients list compared to crisps these days.But Golden Wonders were just one of many popular fried potato products from back in the day - the 1970s saw a variety of popular crisp brands that are no longer sold in supermarkets, such as Bones.In the 80s, it was all about KP and Square crisps, before Monster Munch, Quavers, and Wotsits, with their now-retro packaging, took over in the 90s.1970s The 1970s saw companies like Smiths dominate the British crisp market, with options including Bones Another popular choices from Smiths was the Flavour 'n' Shake bags, which came plain and with a seasoning sachet Back in the 1970s, customers paid much less for crisps compared to today's prices - with this bag of Football Crazy crisps on sale for less than five pennies Golden Wonder, which are still widely available in the UK today, were another popular brand in the 70sIn the 1970s, the British crisp market was largely dominated by Golden Wonder, Smiths and KP, each of which brought out different varieties in a range of flavours.But unlike some of the more controversial flavours that shoppers get today, from Worcestershire Sauce to Prawn Cocktail, the options were often limited to the classics.Smiths, for instance, offered Flavour 'n' Shake crisps, which came plain and with the option to salt.Golden Wonder crisps, which are still widely available in the UK today, were also popular - and branched out with more adventurous flavours, including Smoky Bacon.1980s The 1980s saw bold and punchy flavours reach UK supermarket shelves, including Scampi and Lemon Fries Burton's pig-shaped crisps, Piglets, which came in a variety of flavours, reached the peak of their popularity during the 1980s Square Crisps also became a popular choice - and came in a selection of flavours, including Cheese & Onion In 1986, Walkers offered a free audio cassette tape in their French Fries rangeBy the 1980s, crisps had only gained more fans in the UK, with offerings and the selection of flavours increasing. The decade enjoyed bold and punchy flavours, including Scampi and Lemon Fries, alongside other meatier options.Walkers, a favourite brand among Britons that still reigns supreme today, also surged in popularity, which offered staple flavours like Cheese & Onion and Ready Salted.Other crisps that became popular in the 1980s include the cult-classic Discos and Hula Hoops.1990s Monster Munch Pickled Onion were introduced in 1978 - but became a staple for many in the early 1990s Doritos 3D, the air-filled version of the popular crisp, were originally introduced to the UK in 1998 Walkers took over Quavers in the 1990s - helping make the cheese-flavoured snack into what it is todayBy the 1990s, brands had introduced many of the crisps that the nation still loves today.The mainstream crisps, including Walkers and Doritos, found great success in the era - but as did alternatives.The bacon-flavoured Frazzles became a favourite in the 1990s, alongside snacks like Skips, Nik Naks, and Discos.Monster Munch also cemented its status as a crisp staple in the 1990s, despite being introduced years earlier.2000s Walkers launched the Do Us a Flavour campaign - encouraging customers to vote for the best flavourBy the 2000s, it was all about fun and funky flavours, causing Walkers to launch Do Us a Flavour.The campaign encouraged the public to invent new flavours, which introduced unlikely options like Cajun Squirrel, Onion Bhaji and Crispy Duck & Hoisin.Other products, like Monster Munch, Wotsits, and Doritos, continued to prove popular among consumers.Variety packs, much like today, also became a favoured choice, offering customers a range of flavours in a single mixed-selection bag.
