Asda, one of the UK's best-loved supermarkets famous for its bright green branding, 'rollback' prices and beloved 'pocket tap', is celebrating its 60th anniversary this month.

As the UK's third-largest food retailer with more than 1,200 stores and 145,000 employees nationwide, the supermarket is equally cherished for its George clothing range - currently fronted by supermodel Yasmin Le Bon - and its Living homeware brand.

But despite having been trading as Asda for six decades, shoppers are only just realising what the acronym actually stands for.

And, while the business's origins can be traced back even further - all the way to the 1920s - 1965 represents an important moment when the brand as we know it today was born.

So how did Asda get its four letter name? It all has to do with a merger that occurred exactly sixty years ago.

In 1965, Peter and Fred Asquith, sons of the Yorkshire butcher W.R. Asquith - who forty years earlier had expanded the family business across the north of England by establishing six additional stores - saw an opportunity to further grow the company that their father had passed down.

By now, the brothers had already established a self-service supermarket inspired by the US megastore Piggly Wiggly in the former Queens cinema in Castleford.

And, after the success of that store, they had opened a second one in Edington, with both trading under the name 'Queens'.
