The first HMV ("His Master's Voice") shop opened in 1921 on London's Oxford Street, with an opening ceremony performed by composer Edward Elgar.
During the 1970s it was Britain's leading music retailer. Despite going into administration in 2013, in 2015 it overtook Amazon to be the UK's largest retailer of physical music products.
