I don't know the history behind it, but annual Christmas commercials are a very big deal over in the UK. Massive companies from Disney to McDonald's create special, long form, commercials for the holiday season.
But the big one is from John Lewis & Partners. They are essentially a department store. Their annual Christmas advert is something people look forward to all year long.
While it's not that big of a deal over in the States, I do love these commercials. They're always filled with joy and happiness, even if they bring you tears. This year's John Lewis advert is going to check off all the boxes of emotions you need.
