The advert, which launched at the weekend (10 November), has generated some 6,790 likes and 1,340 shares on Facebook so far and was trending last week on Twitter as buzz for the hotly anticipated spot grew, the retailer claims.

More than half (51 per cent) of UK Twitter users have received at least at one mention of the brand since it was first revealed on Friday (9 November), according to YouGov’s social media measurement tool SoMa. Additionally, the advert has generated more than 89,000 mentions on the micro-blogging site during this period.

The retailer says the launch was the “strongest” it had ever achieved for a TV spot, adding that the video has already achieved more than 1 million views on YouTube .

The ad, which John Lewis claims has reached 14 million through PR coverage, shows a snowman couple in a family garden only for one snowman to disappear the next morning. It follows him on a journey through woodlands and across rivers until he eventually reaches the high street and enters John Lewis to buy his beloved a matching red scarf and gloves.

The final scenes show the snow couple reunited and smiling while a voiceover says: “Go the extra mile this year.”
