Since the 1930s, Coca-Cola has been synonymous with the holiday season. From heartwarming ads and special-edition packaging to the Coca-Cola Holiday Caravan stops that bring holiday happiness to communities across America, Coke and the holidays go hand-in-hand. To embrace and celebrate the spirit of the season in 2016, Coca-Cola is shining a light on "unsung heroes"- those who go the extra mile to make the holidays more special for those around them. A new 30-second TV commercial, titled "A Coke For Christmas," follows a teen as he wheels a cart of ice-cold Coca-Cola through his neighborhood, sharing bottles of delicious refreshment with merry-makers working hard to create a festive season and wonderful memories. From a man hanging holiday lights to a mom tirelessly preparing a holiday meal, each recipient is surprised by the unexpected token of kindness. The final bottle of Coca-Cola is saved for a visit from one last holiday hero: Santa Claus. Coca-Cola developed "A Coke For Christmas" with SRA Rushmore - Madrid. "For decades, Coca-Cola has brought happiness and refreshment to the holiday season," said Melissa Palacios, associate brand manager, Coca-Cola Trademark, Coca-Cola North America. "We're embracing the spirit of unsung holiday heroes through our TV creative, but we aren't finished there. Through special packaging and our Holiday Caravan's cross-country tour, we'll touch millions of Coca-Cola fans and unsung heroes with heartwarming, uplifting experiences." The brand is also encouraging teens across America to showcase the different ways they step it up during the holidays through a #WeSleigh social campaign. Through it, fans can interact, share their holiday photos and recognize fellow teens.
