The John Lewis Christmas advert is a television advertising campaign released by British department store chain John Lewis in the build-up to Christmas. John Lewis launched their first Christmas advert in 2007. It has since become something of an annual tradition in British popular culture, and one of the signals that the countdown to Christmas has begun in the UK. The adverts tend to attract widespread media coverage and acclaim upon their release.
The songs used in the advertising campaigns are generally covers of existing songs by popular artists. They have often reached high positions on the UK Singles Chart, and the original versions often receive a sales boost. Ellie Goulding, Gabrielle Aplin, Lily Allen, Aurora, Tom Odell and Vaults are among the artists whose music has appeared in a John Lewis Christmas advert.
London-based agency Adam & Eve/DDB have produced their adverts since 2009. The adverts have led to some fierce competition, most notably from Sainsbury's, Marks & Spencer and Boots. Wikipedia
